So i just got a 2002 ep3 used and the keyless entry system is acting all wierd. When i hit the lock or un lock button the lights will flash like it is locking or unlocking but the doors don't lock or un lock. Well sometimes the passanger door will un lock and lock but the drivers door does nothing. I already replaced the battery in the remote. so whats wrong? I appreciate any help

 

take it to the dealership would be my best advice.

 

Just reprogram it and see if it wortks !!!

 

pm me if you want to know how to reprogram the remotes
