to the mods: im not sure if im posting this in the right forum. pakilipat na lang po kung mali...

the problem is with a starex club - 2000 model. this unit came with a factory installed remote-alarm system. strangely, it only came with ONE remote control. this remote control suddenly stopped working. we tried replacing the battery on the remote but nothing happened (we are not sure if its the remote or the main alarm unit thats faulty). so to lock/unlock the car we had to use the key to open the door. since the remote control has always been used everytime, we discovered only now that the mechanical door locks were stuck up! the one on the passenger side was solved by spraying WD40. unfortunately, the door lock on the driver side is still stuck. can anybody refer a good shop who can:
1. diagnose/repair the remote control/alarm system
2. fix the mechanical door locks.

thank you in advance to all who can assist
