My Dads 2002 Es 300 Has A Door Lock Problem. Please Advise

[2002es300TX]

When he uses the remote to unlock the doors 3 of the doors unlock but 1 does not. Any idea why this is happening? Is this common?

The problem could be a failed lock motor/actuator/solenoid -- people seem to use different terms for the same part. It is not a real common problem but certainly has been reported multiple times for the ES on this forum. Do a search on "actuator" or "lock" in the ES forum and you will find other threads about this problem. Here is a diagram of the front passenger door that shows the lock mechanism: http://www.toyodiy.com/parts/p_U_2002_LEXU...EAGKA_6703.html

Thank you for the reply. I should have been more specific. The drivers lock doesnt open but the other 3 do. :)
