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.
If you can't open one door, try another door to see if it opens. If all of the doors remain locked, the issue may be with the remote lock or a damaged lock itself. In most cases, when a single door will not open, it's due to a broken latch – which will require replacement.
If only one door isn't working, there's likely a problem with a door switch or sensor. If this is the case, you'll need to have a mechanic take a look at your car. If all of your doors don't open, you could have a blown fuse.
If all doors are locked and vehicle / outside temperature is warm, then only driver's side door unlocks. If all doors are locked and vehicle / outside temperature is cold, all doors almost always unlock. Pressing lock / unlock too many times in quick succession eventually causes driver-side door to stop unlocking.
A fuse is blown: If one door doesn't work, but others do, the problem could be a blown fuse. Replacing the fuse will correct the problem. This is a cheap and easy fix. The solenoid is bad: Again, if one door doesn't work, but others do, the problem could be with the door lock solenoid.
By keeping this door locked all day, store owners don't have to wonder whether some careless closing clerk forgot to trip the mechanism on his way out, thus more peace of mind. It also can be an issue of safety.
The cost to fix a car door that won't open from the inside can range from $100 to $500 or more, depending on the type of car, the cause of the issue, and the complexity of the repair.
The keyless entry system receiver(s) on your vehicle may not be picking up the signal from the key fob. Try holding the fob right next to the door handle when pressing the unlock button. If it unlocks the door, the problem may be a weak battery in the key fob, or a problem in the keyless entry antenna or wiring.
It will normally cost between $200 and $600 to fix a car door lock, depending on the problem and the type of vehicle you drive.
Faulty wiring in the car door system can lead the door controls to malfunction. Insulation wears are the primary cause of faulty wiring. By taking your car to a shop, automotive technicians can install a new wiring system to ensure your car doors are working properly.
The manual buttons are located on each door and unlocking one of them will unlock that specific door. Old cars with no electronic locking mechanism don't have an automatic unlock button, they can only be unlocked by engaging the manual unlock button on the door, or by using a tool to pull the handle from the inside.
Try rebooting the door lock by removing the batteries. Removing the batteries will force the device to reset. Then, check the security panel (or control panel) to make sure that the door lock is appearing on the list of connected devices. If it is not appearing, reconnect it.
Try a lubricant
If you have a stuck door lock, spray lubricant into the lock's keyhole. Doing so will loosen any debris or deposits sitting inside your stuck lock and prevent your key from turning. Insert the key and rotate it a few times to work in the lubricant, releasing the stuck part.
The average car actuator replacement cost is about $400, including the cost of labor. But exactly what you pay will vary depending upon your car's make and model, and can range from as low as $70 to as high as $900. In most cases, a mechanic will remove the malfunctioning actuator and replace it with a functioning one.
Over time, moisture, oil, dust, and debris can enter the actuator or the mechanical links. These will react to form rust, which will weaken the mechanical links and can cause failure of the actuator. Accidents and other physical stresses can cause door lock actuator failure as well.
