Hi,
My daughter has a 1998 Magna, her LHS front central locking unit has stopped working.
Is it possible to:
1. Purchase just one of these systems?
2. Can you use generic parts?
3. How difficult are they to change?
4. If able to use generic, is it plug and go?

Have found many posts about central locking using search, but so far have not found any that answer the above.
