Problem About Is200 Keyfob To Lock The Door

[NaYu]

Hi everyone, I am new for is200 and also for this forum. I have a problem with my 2000 is200 keyfob.

As normal, when I push the lock button on my keyfob, the thief detection system will be actived (beep and light once);the front mirror will be closed and the door will be locked.

However, a few days ago after I wash my car, problem happen!! When I push the lock button, the thief detection system can be actived and the front mirror will be closed, but the door cannot be locked!!

For now, i need to close the door by key and than active the thief detection system. Anyone have any ideas for my situration and what can I do??

Thank.
