Autounlock unlocks all the doors when: Your vehicle comes to a stop and you switch the ignition off or to the accessory position. You open the driver door within 10 minutes of switching the ignition off or to accessory.
Did you often leave your vehicle`s door unlocked? Well, if you own a new Honda vehicle, you get a fantastic feature called Walk Away Auto Lock®. As its name implies, it automatically locks the doors of your Honda when you walk away from your vehicle with the key fob.
To program your keyless-entry remote, press and hold the “LOCK” and “UNLOCK” buttons on the key fob simultaneously until the locks cycle once more. This could take up to 30 seconds, so be patient.
In most cases, there will be a button or switch near the door handle. Once you have found the correct door, press and hold the button or switch for a few seconds. After a few seconds, the door should auto-lock function. If it does not, try pressing and holding the button or switch for a longer period of time.
The ignition lock cylinder is a mechanical part where the ignition key is inserted to start a vehicle. It`s mounted inside the ignition switch, the electrical component that locks the ignition and “reads” anti-theft coding in the key to allow the vehicle to start.
The driver usually has control over all the car`s locks, while passenger door lock controls only affect those specific doors. Many 4-door vehicles feature child safety locks which prevent rear passenger doors from unlocking or opening from the inside, overriding the power door locks on those doors.

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.

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.

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 : 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.

Only the driver’s door will unlock with the remote or door switch
ANSWER : Hi there. On your particular vehicle, there is a central control that receives the signal from the key remote and relays that information to the other locks. This could be the component that is damaged. To be certain, you might want to have a mobile technician, such as one from YourMechanic, complete an inspection to diagnose your door lock problem so the right repairs can be made.

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.

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.
