I got 2 remotes with my TJ EXE Magna. One that works and one that has a flat battery.

Just this tuesday, I took my car to service at one of the Mitsubishi dealer and was told I can't replace the dead battery but need to replace the whole remote + reprogram @ ~$75. They said to try to open the unit would crack the plastic casing, making it useless. I refused this since my other remote still works.

Anyway, when I try to use the other working remote tonight, I found out the remote stop to work. I suspect they did something to the car that stop receiving remote signal or something like it. Is there a remote receiver switch in the car they forgotten to turn back on? I can't find any reference to it in my handbook. I hope they didn't do this to force me to pay ~$75 to replace the remote with dead battery!

Thanks in advance.

there's a way to reprogram the remotes in ur manual. Like u turn the accesories on and off 5 times quickly then press a button on the remote. something like that

Yeap! if you have the manual, it should be correct! Just do a check.
Is it difficult to open up the remote with flat battery? Ply it slowly it should be ok.

instructions:
Procedure for replacing the remote control switch battery
1. Remove the screw from the back of the remote control switch and open the switch
2. Remove the discharged battery
3. Install a new battery with its positive side + down.

4. Insert the pawls first. Then taking care not to dislocate the O-ring assemble the switch
5. Check the operation of the switch on the vehicle.

To program the remote control
A maximum of 4 remotes can be programed at any one time.
When programming an additional or replacement remote, all previosly programmed remote control switches will be erased and therefore will not operate the door lock. These must be reprogrammed at the same time.

1. Enter programming mode by unlocking the vehicle, turn the ignition switch to the "ON" then "OFF" positions 3 times within 5 seconds, finishing in the "ON" position.
The vehicle is now in programming mode
2. Within 5 seconds operate the button on the new/ existing remote control switch.
The turn signal lights will flash to indicate that the remote control switch has been programed
3. Within 5 seconds of the operating the button of the remote control switch just programmed, operate the button on the next remote control switch. The turn signals lights will flash to indicate that the remote control switch has been programmed.

Note:Should u fail to operate the button within 5 seconds, the vehicle will exit programming mode. Programming mode must therfore be re-entered and any previously programmed remote control switches must be re-programmed.

The above are for Magna TE, do not know if they apply the same to yours. But this gives you a rough idea what we meant.

Cheers!

Awesome info dude!! :D Cheers for that... I was wondering why when I reprogrammed on I lost the rest :nuts:

Thanks guys for the detail info. I manage to re-program the remote with the info given. :thumbsup:

The remote doesn't have a screw at all, but I manage to pull it apart without breaking anything. It's a rip off to suggest the only way to replace a dead battery is to replace the whole unit.

i have replaced battery in my keyless remote and LED still flashes , but when i try to program it to car nothing happens.... is there a fuse or something to the imobiliser in the car that i can check to get my keyless entry to work again , cause id hate to have to fork out some money for a new keyless entry

Anything above the TH have different remove control and there are no screws. I tried opening one of mine but doesn't seem to wanna open. I heard there is a way, but who knows.

its only the TE & TF magnas that you have to replace the whole unit as you can't open them, but anything above you just pull apart replace the battery and reprogram if you take too long to replace the battery ;)

Do you guys find that the range for the remotes on the TH above to be Sh-t house they only work if your like 3m away from the car!!!!!!

that's actually not a bad thing and they prob did it on purpose! my colleague's pulsar could be unlocked from the window of our third floor office :shock: it would be easy for car thieves to EASILY locate your car if you dropped you remote

yea i guess n see your point, but then whats of having a panic button on the cars remote if its going to be too late to use the dam thing????? not that i have ever had to use it but if the day came????
its the only car that i have had with such a low range remote. . . . . .

Isnt it the other way round? I just listed instructions on how to replace battery for the TE.
lol, dun worry take it easy. I am trying to help with my best knowledge I have with my 3rd gen magna.

I do not know each one's habbit of using car keys but basically my keys are attached with the house keys, I find it better that I wont loose either of them. Personal perference.

There are 3rd party car remotes that cost cheaper. They can be alternative replacements.

Range limit is 5m, anything less means your battery is going weaker and needs replacement, according to manual.

Cheers!

never got more than 5m out of mine.

Sorry my mistake I meant maximum range is 5m, and it goes weaker till about 3m which suggested for changing.

with the TE magna remote control there is no screw, if the flat battery is flat how would you proceed to replace it?

Thanks all for this thread. I just came back from our local dealer who said the battery cannot be replaced and a new remote would cost $65. I followed this thread, replaced the battery and everything works great. The battery cost $3.50.

Isnt it great when dealers try and stooge u, should take it back and tell them.

For the TH/TJ, and I assume later, remotes to change the battery you have to carefully pry the halves open at the seam with a blade of a screwdriver or knife, hence the need to be careful! Can't remember the actually battery type, but it's worth mentioning that the later remotes are prone to cracking the solder joints, mine did.

yea i guess n see your point, but then whats the point of having a panic button on the cars remote if its going to be too late to use the dam thing????? not that i have ever had to use it but if the day came????
its the only car that i have had with such a low range remote. . . . . .

I agree..

And as for the low range.. its stupid.. If its pissing with rain and your parked at the back of the car park (like i usually am) then you have to stand next to your car continually pressing the button for it to open.. i mean its no MAJOR problem.. but the remote for my lancer was excellent.. you could lock/unlock the car from inside work..

best remote control system i have seen is on my grandparents honda.. will lock from ~25 meters away, wont unlock unless within ~10m and panic alarm can be activated up to ~25 meters away aswell..

another gripe.. the magna remotes (TJ's etc) with the green and red buttons, they suck to press.. you have to push it really hard sometimes for it to work, have used much better ones by mitsu.... ghey!

Amen to that. . . . . :D i thought it was just my remote that was hard to press the TE on mums is soo easy and has a really good range but ours suck . . . . :confused:
Too true about the rain!!!!!! had that happen to often especially when you holding a ****e load of documents and want to get into the car asap>>>>:cry:

You got a point!!!!
I never realised this as I was writing out from the manual. ****.
As my remote is new, dont feel like plying it just to see it lol.

I look into it and get back.

"Edit"-I have tried to ply but it seems like I am going to damage it so I say, I leave it for now, sorry. Did anyone manage to ply theirs out give some tips?

Cheers!

Yes, I pried mine open with a nail file. Eventually it pops apart. The battery is held in by a clip and sits in a holder of its own. The battery can be gently levered and pushed out. The battery holder has two metal probes that go into the circuit board via two small holes. Getting the battery out without pulling the probes out is the tricky bit. In my case the probes had already come out from the shock of having been thrown downstairs on many ocassions and not being caught! I put a new battery in anyway and went through the "turn on five times" ritual and it worked. However the probes came out again with normal use. To fix this problem I used a bit of blu-tac to hold it in place. this also gave better "Compression" when the cover was replaced and there is no loose room for the probes/battery holder to come out again. Hope this helps someone.

Thanks mate! that should update the guys here. I know it can be done, it was just that my remote was new and just didnt want to scratch and force it at that moment.
Hope this helps for those who wondered how to open for the TE models.

Cheers!

Yay, finally have my keyless entry problem fixed. I can confirm it works for a 99 TH auto.

on my th i changed the batery and got everyhting working but about 1 month later it has stoped working, and its real strange cause i chnaged the battery in me spare key and hadnt used it till the main one started playing up and it had the same problem, is this like a reciever problem? i tried reseting and it worked once and dosent work any more.

This forum just saved me some more money!

Both my remotes stopped working at the same time!
Jumped on here and followed the turn 3 times etc proceedure and got one working but not the other. So using a flat head screwdiver I pryed open both remotes (they come apart pretty easy just do it a bit at a time) and noticed that the tab securing the battery holder to the PCB had come loose on the GND side. A quick dab of solder and another program they are both working now! :D
I resoldered all the battery holder pins just to be safe as they all looked like they were nearly gone.

Thanks guys!
:D

I've noticed that if i point the remote at the car and it doesnt work, and then i point it at my head and try it, it works really well :shock:. Maybe im just crazy :nuts:, but if it does work then maybe i'll end up with brain damage or cancer :redface: :nuts:

hmmm tonkins said the same thing... they said point it at your chin and it uses your head like an antenna... I thought they were just being morons... Im still not convinced, so has anyone got a logical explaination? Im in electronics as a job, and I cant see how it would make any difference...

mine works no matter which way you point it... only i cant be any more than about 2m from my car for it to work :rant:

My TE Remote doesnt have a battery holder at all, The battery is spot weleded to two termanals, then soldered to the board! Thankfully the battery is OK, but the tactile switch is buggered, along with the rubber cap.

Yes, I cracked the solder joints too. And I don't have an iron :(

Bah i dont know whta the hell is wring with mine... The remote stopped working one day and i tried to reprogrammed and not working. Ive gone through 2 batteries in just ove 6 months. They should last longer than that shouldnt they! I did the turn the key 3 time thingy and the blinkers dont flash. Usually when u press the button on the pad it will make a buzz. checked the fuses to no help...

Have you dropped the remotes? This is the easiest way to kill them. Oh, the local dealer replaced mine under warranty while it was in for other warranty work.

a while ago i fit an aftermarket alarm in my vrx n had 2 remote layin arround and they still work on my car, now my mrs car TJ advance needed another remote, so i don wana buy her a new one while had 2, so i programed 1 to her car with the normal proceedure n end up workin perfectly... the problem is that same remote now open both cars, if u press the unlock button both car will open but in my vrx the aftermarket alarm will go off...
is there a way to stop that remote from opening my car?? when i called mitsu they said to reset the computer in my car by disconnecting the battery which i did but didnt work, still that remote open 2 cars...
any idea guys n sorry cldnt find anythin in the search so i had 2 update this thread...
thx in advance
cheers

Pop your car into programme mode but dont programme a remote into it, this should clear the remotes from your system

Mits told you to disconnect the battery, they must have disconnected thier brains

Mits remotes are rubbish, I got a brand new one for the TF, 3 months later the section for the keyring is broken, now need to work out how to glue something back there so I can use it again

BTW the KE had a 3 button with screw on the back where as the Magna had no screw on the back. The Verada had ETACS where the magna is more just remote unlocking and has not immobiliser built into the remote set up. If you lock it with your window down in the TE/F you can still reach in and start the engine where as with the Rada it will not go

Engineering fail there. hahaha

']Engineering fail there. hahaha

Looks like I'm sweet then :) TH ftw.

In mine (TJ) you can lock yourself in with the remote, then just unlock the door and open it without anything happening.
any idea guysTry English.

My remotes never work properly, I've got two and both stop working every couple of days and have to reprogramme them each time, and the range seems to vary wildly day by day. Remote boot release is hit and miss too.

Boot release is the ONLY thing that works on mine :-/

Boot release is the ONLY thing that works on mine :-/

Ha! Mine too..... I stiffed (yes stiffed) the Mitso immobiliser and fitted an aftermarket alarm with CDL etc... only use the mitso remote to open the boot......

I have a workmate with a TJ exec and I'm always changing batteries.... got it down to a fine art now...

Crack it open... (I use the special tools to open the early Ipods) and with the new battery in my hands... shielded with my t shirt or a soft cloth to stop my fingerprints getting on it... quickly pop the old one out and then pop the new one in....
Never had to reprogramme a remote that way...

Also helps if you purchase a excellent quality Lithium cell... cheapies from the $2 store just don't last that long..

5c piece works for that.

If I lock the doors with the remote then try to open the car from the inside my alarm goes off.

Remember that Verada's have an alarm where a lot of Magnas just have keyless entry

5c piece works for that.

If I lock the doors with the remote then try to open the car from the inside my alarm goes off.

Mine too :P I managed to set it off at mac centre one day.

Setting the alarm off when opening the door from inside is intended to allow you to check the operation of the alarm
Refer section 6-30 in owners manual

I have a TW VRX.

If i locked the car with the remote but unlocked it with the key, the alarm goes off. Is'nt there supposed to be a microchip in the key that identifies the key to the car? Does this mean i need to reprogram?

This concerns me if one day I remote locked the car, and the battery goes flat upon my return, the key would be useless.

the alarm will go off because the car has been unlocked in a different way to the way it was locked.

ie - you locked it with the remote, but unlocked with the key.

there is not a chip in the door barrel to recognise the key - the car just knows that its been unlocked by 'a key' and the door has opened.
the receiver chip is in the steering column for the imobiliser.

IF you locked the car with the key, and unlocked with the key, the alarm wont go off.
i believe that the car alarm will also still work too - maybe check your manual on that one

EDIT - even if the battery is flat, the key will still unlock the door to let you in the car, just when the battery is hooked to another (to jump start etc) the car alarm will go off. then you have to hit a button on the remote. or do you mean the battery in the remote?

I know this is an old thread, but just to say my remote was busted and I decided to carefully saw it open.

Doing it properly you should be able to remove the battery from the solder and replace with a battery CR2032 litium battery and it will work without the need to reprogram again.

Total cost $3.95

but can be improved by plastering the unit with moldable plastic to seal it again.

you shouldn't need to saw it open... it will just clip open! It's a press fit...
