This sounds like some sort of an electrical issue. I recommend checking all fuses relating to the windows. Rather than removing each fuse, you should be able to use a circut tester that you can pick up at your local parts store. If you find a fuse to be blown, replace it. If this does not solve your issue, I would enlist the assistance of a qualified technician who specializes in electrical systems. If you find you are needing assistance with this, a certified technician from YourMechanic can come to your home or office to inspect your electrical system.

It could be a dead battery or a glitch in your key fob programming. A simple battery replacement can sometimes solve the problem and is an excellent place to start when solving your door locking issues. If you need a key fob replacement, you should go to your dealer if you want a key that will function properly.
The Power Locks Don`t Work

A problem with one lock is probably due to the lock actuator or another malfunction inside the mechanism of the door itself. But if none of the power locks work, check the fuse box in your vehicle. A blown fuse can cause the power locks to stop working.

Chances are, the switch is simply not allowing enough voltage through to actually unlock the doors. Again, check the unlock button for a poor wiring connection, a dirty switch, or any other sort of obvious damage. If nothing seems to be wrong, it is a good time to do electrical testing while you have access.
A malfunctioning logic board or a break in the wire could cause problems. If the lock and unlock function works intermittently, there could be an electrical short in the system due to the plastic insulation of the wire being worn down. If it has ceased to function at all, the wire could be broken.
The door locks are electronically controlled, and as is the case with many other automotive electrical circuits, they will run their power through a relay. The door lock relay is the relay responsible for sending power to the door lock actuators so that they can lock and unlock the vehicle.

The solenoid lock denotes a latch for electrical locking and unlocking. It is available in unlocking in the power-on mode type, and locking and keeping in the power-on mode type, which can be used selectively for situations. The power-on unlocking type enables unlocking only while the solenoid is powered on.
A bad battery in the key fob is most commonly the reason for a failure to send signals to the keyless entry system. If it is available, use the spare key fob to open the vehicle and start the ignition. If the spare fob is not available, use the provided key embedded in the fob to unlock the door.
The cause of the lock malfunction is a dead-latch failure. The dead-latch is used with key operated doorknobs or levers. The dead-latch is designed to prevent a burglar from pushing the latch back with a knife or ice pick, this is often called “jimmying,” the door open. The dead-latch has a button next to the latch.

Door lock problems
ANSWER : Hi there. There is a resistor for the door locks that keep a voltage on the driver door lock cylinder to activate the secondary door locks electronically. If the resistor is leaking (losing power) it tends to cause the door locks to not work. You can try unlocking the driver door, then open the driver door and use the key to unlock the other doors. This will supply power directly to the driver door lock cylinder and bypass the resistor. If the other doors unlock, then the resistor needs replaced. If the doors do not unlock with the key and the driver door open, then the door lock cylinder on the driver door will need replaced. If you need further assistance with your doors not unlocking when turning the key twice, then seek out a professional, such as one from Your Mechanic, to help you.

ANSWER : Hi there. In general, wiring harnesses are sold by the manufacturer as a whole harness; not individual wires. It is much easier, cost-efficient and safer to replace the entire harness if it’s determined that it is faulty and the source of your alarm / door issue. It would be best to have one of our mobile mechanics come to your location and complete an electrical problems inspection though, as it’s possible that this issue is related to an error code trapped in the ECU. If this is the case, simply clearing the code will resolve the problem. If the issue is determined to be the wiring harness or an exposed wire, they can recommend and most likely complete the repairs as well.

Having problems with door locks on 08 Cadillac CTS. Driver side door especially and will not lock or unlock with key. Others loc
ANSWER : This is often related to a malfunctioning door lock actuator, a blown fuse or a faulty power door lock switch. When you use the door lock switch in the car it sends a signal to a relay which then activates an actuator inside the door. The actuator is the final step in the process in that it is a small motor with a set of gears that actually locks and unlocks the latch mechanism inside the door allowing the door to open. When this motor is bad, the latch mechanism will fail to operate and cause the door not to unlock as it is designed to. In the case of a bad door lock relay, the power, normally needed to send the signal from the switch when you activate it to the actuator motor is not there. This means the relay is not allowing the circuit to be completed and the actuator motor is not activated. Any of the above may cause your power door lock switches not to work properly and should be diagnosed by a qualified mechanic. I would suggest having a professional from YourMechanic come to your location to take a look at the door locks in your vehicle.

ANSWER : Your central locking system may have been designed with a control module in the circuit. This is a small computer that is responsible for controlling the different functions of a particular system. It is possible that the module for your central locking system may have shorted out internally preventing particular functions from working properly. I would recommend having a certified technician test your central locking module to determine if all of its functions are working properly.

Doors wont lock or unlock with fob or switch?
ANSWER : Hello. Further testing should be done to help solve your problem. Being that the door unlock reprogramming procedure has already been done and the fuses have been checked there’s not much left it could be. When you hit the unlock button you should hear a little noise in each of the doors. If you hear the noise that means that the motor inside of the door actuator is working therefore it is likely the actuator itself as the problem. Though if you do not hear any noise that means it is likely the motor inside of the actuator. The actuator motors are very common failure on Lexus. The Lexus Community is almost an uproar because the a L in Lexus should also stand for luxury but there have been widespread simple problems reported such as this. A technician such as those we have here at yourmechanic will be able to diagnose your door lock issue for you firsthand. But if you consider following the test I suggested that should help you narrow down to a solution as well.

It may also be a beneficial to take a door panel off and probe a multi meter to the door actuator connectors to ensure they are receiving the proper power and ground when the buttons are pressed. If they are that only leaves two things that can be at fault. The door actuator or the motor inside of the door actuator.

After unlocking the car from the drivers side, if the passenger door is opened before the key is put in the car the alarm goes off.
ANSWER : The key should only unlock the driver door with one turn and unlock all of the doors with two turns. If the passenger door is unlocking when the driver door is turned with one turn or if the alarm is still set if the driver door is turned two times, then the Immobilizer System Module needs replaced if you are intending on not using a key fob or you will need to get a key fob to manually turn off the Immobilizer System Module. If you need further assistance with your doors unlocking unusual, then seek out a professional, such as one from Your Mechanic, to help you.

Wondering what the range for door handle auto-unlock is?
ANSWER : Hi there. Typically you have to be within 10 feet of the vehicle in order for the remote key to link with the security system on the car and to activate the manual door unlock button. You should be able to find this information in the vehicle’s owner manual. If you don’t have one, feel free to contact the local Dodge dealership or search online and download the manual so you can clarify this question.
