Hello, I am a new owner of a 1991 LS400. The car has a couple of issues with the keys. The driver's door handle is broken, and the lock is not working properly. I can open but not lock the car using the key. The lock cylinder in the truck is missing completely, and the master key is missing its button, which I understand triggers keyless entry.
It doesn't seem worthwhile to pay a lot of money to get back to a 1991 style keyless entry system. I am tempted to update to something more modern, with a better range, remote trunk access, etc. I am trying to work through the maze of options (e.g. at Autotoys), which is made more difficult because I don't really know what the car has already in terms of security, or what can be done. I don't want to spend a lot of money, but if I can get a basic keyless entry system for $40 or $50 that would seem to fit the bill. Any advice?
Also, how easy is it to swap out the lock cylinder?
