Ok!

Whenever i lock my car, doesn't matter how, be it with the remote or manually locking it from inside the car, the car will immidiately unlock itself! Every door!

I'm freaking out a little here because this means that i cant really take my car anywhere because i cant secure it! AAHH!

Any ideas?

there maybe a relay behind the dash on the drivers side
if you have a factory manual its in the electrical loom section

I had this issue when I ran a speaker wire thru the little gommet between the drivers door and the chassis.

Turns out I had snapped a wire in the process. So I had to slice into my gromment and repair the wire. Hopefully you dont have to do this.

i know my car, and i think yours to, has a mechanism where if you lock the car but it thinks that there is a key still in the ignition the car will auto unlock. Perhaps something in the barrel is stuck?

Just my 2c
