I just bought an 03 EP3 and the past few days the fob hasn't been locking the doors. It will unlock them fine but when I press the lock button it doesn't work. If I manually lock my door with the key and then press the lock button on the fob it will sound the horn and arm it. Any ideas or has anyone had this issue?

Thanks.

 

If you are pressing the button to lock and nothing happens it should's like the actuators is finished.

It's a known issue for these models to have weak actuators luckily they are pretty cheap to replace.

I had this exact problem with my EP3 and once changed it solved the problem.

 

agreed sounds like an actuator
