Question
Dear Zak,

My 99 Rx 300 has a weird problem.At first the rear passenger door lock was paralyzed it wouldnt open or close with the keys or the switches from the inside then miraculously after a couple of days it cured itself and was working like nothing ever happened. but now the front passenger door is doing the same any suggestions on the reason for that and any fixes  you suggest. Also i had the inside of my master key lost (the back broke and the inside electronic part fell off) i got the inside from a friend  anyway to programm it to work with my vehicle.

thank you so much for the service you provide.

Aamir

Hello, As far as the key locks the first thing that needs to be lokked at is key or lock wear. This is the number one problem. As far as reprograming the dealer is the only one that know the process for this. There are several steps involved ond only a few top people at the dealers know how to do it.
