My power doors unlock but won't lock (I also have an aftermarket alarm system). This is the case for both front door power 'locks'. Is there a simple fix to this?

The alarm turns on when I put the key is in the door lock. Is there alarm reset?

Are you using an aftermarket key or the original? It may have a chip in it. Also if you have a spare original try it.

had a similar problem with a hyundai coupe , this turned out to to be the door lock mechanism in the drivers door, so could be the place to start, as i would have thought that generally the power locking technology is the same universally

Flashing lights on security system for 1993 ford escort wagon

usualy there is a switch on the driver and passener side, try disarming by unlocking drivers door with the key to disarm the factory alarm, or the passenger door. this should turn off the alarm if it is not aftermarket. the factory alarm will arm any time the door is locked by key or power door lock. good luck

Apparently your aftermarket system is installed incorrectly. The door locks should have power to them even with the ignition off. Possibly whoever installed your system used a switched power wire to power the system or if the system requires one switched and one always on power line then they have them connected backwards.

Car door alarm activation

Need more info. Is it an aftermarket alarm? What kind of car? If it is an aftermarket alarm, it is possible that the wiring to the alarm module could be configured wrong, making it think that someone is hot-wiring the vehicle. Or, it could be that the wires to the alarm are chaffed, and the power from the alarm is shorting to the door lock controls. If neither of those are an issue, then it could also be the settings on the alarm module itself (many aftermarket alarms are pre-programmed to lock the doors, as soon as the transmission gear selector is placed in "Drive", and if the wires are chaffed, shorted, or improperly connected, it could be that it's seeing the door pin switch, as that trans selector input). In any case, this sounds like an electrical problem for a skilled automotive electrical technician, because many of the vehicles panels may have to be removed, so that the wiring can be exposed & inspected. Without more details, I can only post a "professional opinion", rather than a "solution". I hope this helps.

2003 Monte Carlo SS, FOBS won't unlock doors (new batterries), use key and open the door with the door open FOB will lock and unlock the door, shut the door and the FOB won't lock the doors. After...

If the passkey is messed up, there will be a light on the dash that says security, or have a picture of a car with a lock thru it. If there is no light when the key is turned forward, then its NOT a passkey problem.

Bought from dealer with no keyless entry. alarm activates when doors are locked with power doorlock system. alarm sounds when we open the door. how do we de-activate the alarm before unlocking the door?

Opening the drivers door with the key is supposed to shut down the factory security but the drivers key cylinder usually goes bad. You will have to unlock the rear tail gate lock cylinder with the key and that will shut down the factory security, before opening the drivers door.Your other option is to have an aftermarket keyless entry system installed, which will open the doors remotely while shut down the factory security at the same time.

The security system wont disengage and let me start car what do i do?

This depends on if its a factory alarm or not,if its factory then try using the key to unlock the door if it doesnt work on the driverside then unlock the passenger side door this is due to a bad door lock switch on the driver door, if its aftermarket you nned to look under the dash and find the wire for the starter coming down the steering column, you will see a yellow wire i belive the wire will be cut in half and connected to two diffrent wires, cut it and connect it back together and it will start you will then need to look further for fuses on alarm wires and remove the fuses as the alarm module is bad, a good way to tell its a factory alarm is the trucks horn is the siren, if this is the case then its probably factory and door switch is bad in the lock so try pass/side lock.hope this is helpful.

Power door locks move but won't lock/unlock

I had this problem with the door locks also and it was the door look accuators were striped out. Most locking accuators use a type of motor gear which is plastic. Over time the plastic becomes hard and the teeth break off. You can get these new or used on ebay or get some aftermarket accuators from a car alarm installer. Hope this helps. Terence
