Car details:
=========
Honda Accord 2004 LX
Mileage - 113K
Bought recently from a car dealer


I am ALWAYS able to unlock the doors using the driver or passenger side "unlock" button but the "lock" button doesn't work every time.


Form my observation I can say that the "lock" button is more likely to work -
- after I have driven the car for sometime
- during hot weather conditions

Once it works, it continues to work for the next many hours.

I have replaced the driver side power switch but even that hasnt fixed the problem..

Appreciate any help in isolating the real problem...
