Auto Door Locks Repair – Fixing a Power Door Lock Actuator Over time, a power door lock actuator will begin to wear out. It may also be affected by electrical problems like a blown fuse or damaged wiring. Sometimes, worn bushings can cause the door to operate slowly or in a random manner. Be aware of the movement of the parts as you pull and push the door handle. Unlocking While door locks may be an expected feature of vehicles of the present but they're also among the many things that could fail. Whether the problem is caused by the battery of the remote being dead, an electric motor or actuator wearing out wires corroding, or the simple possibility that a door was left open, the result can be frustrating and even dangerous if your vehicle can't be locked or unlocked. Depending on the model of car, there are different ways in which doors can be locked or unlock. Certain cars have keys that are connected to a door handle, which requires an actual lock. Other vehicles use a button inside the door or the keyless entry system, a remote or some combination of these. If you're noticing that the door lock you're using isn't responding to your request, the most likely cause is the power door lock actuator. It's not uncommon for them to break down after a decade of regular use and then cease to function. It is usually possible to identify the issue quickly using a digital multimeter. You'll hear a whirring sound when the gears spin and a quiet clunk as the latch bolt completes the cycle. If the power locks do not work at all it is possible to remove the door panel and test the lock solenoid with an alligator clip or a different method. In certain models the door lock switch directly controls the lock actuator inside each door to turn off and on. In other vehicles that are more complex, a body control unit manages the functions of door locks by interacting with other systems in the vehicle. If a door lock actuator fails the door won't lock or unlock and the door handle won't move. The door may be difficult to close and the striker or hook latch could jam. A gentle hammering with WD40 can sometimes fix these problems. However, you might have to replace the parts. Unjamming Modern car doors employ the combination of electrical, mechanical and key-operated components to open and close. They can also be powered by electric motors which can be controlled using a key or remote control system. It can be difficult to get to where you'd like to go when one or more of these components malfunction. A damaged actuator could, for example prevent the door from locking and unlocking after the key was turned inside the car. It's easy to fix this problem yourself at home using some basic tools. The most frequent reason for a power door lock to stop working is that the actuator itself has failed. It can happen due to a variety of reasons, like exposure to moisture, which over time leads to corrosion that alters the electrical connection. Dust, dirt and oil can also build up in the actuator, putting an extra strain on the mechanical component. The actuator could also be physically damaged by someone trying to jimmy the device. If you suspect your door lock actuator is defective, the first thing to do is to determine if power is actually reaching the actuator. If so, the problem could be elsewhere, such as an overblown fuse or relay or a damaged controller module. If you've found that the actuator itself is defective then it's time to take action. You'll require a few tools like a wrench and screwdrivers. You may also require removing the door's panel to access it. You'll also have to unplug the cables and wires that are connected to the actuator. After the old actuator has been removed, you'll need replace it with a brand new part. Before you install the new part, you should re-connect all of the cables and wiring, and then conduct a an extensive test of performance to ensure that the door lock actuator is functioning correctly. Check that the new piece is securely attached to the panel's inner surface and that all clips, clamps and other parts are securely fastened. If they are loose, they might rattle or fall during operation. Keyless Entry The convenience of keyless entry allows you to unlock your vehicle without having to insert your keys to the lock cylinder. It works by allowing the vehicle to know when your keys are within reach and then transmitting an electronic signal to the fob that matches that code. The fob relays this to the door locks, which open or close in accordance with the code. Keyless entry is more convenient to use in colder weather, when you're wearing gloves, or when your hands are full. They are also safer than traditional locks since they do not require the key to be put into the cylinder. The technology behind keyless entry systems is complicated. This increases the chance of malfunctions when they do occur. If you're experiencing issues with your power door locks you should consult the owner's manual for directions on resetting the system. Most of the time it will require disconnecting and reconnecting the battery, or pressing a button located near the door lock actuator. If the power locks don't lock or unlock, it's a good idea determine if the issue is present in all doors. A faulty lock actuator may affect other systems within the car, such as security and convenience features. A damaged door lock actuator may not only prevent you from opening your car doors but it could also make the vehicle vulnerable to theft.

These tools are used to search inside the lock, usually between the knob on the door and the power-lock actuator. Once they locate it they can pull on the strip to pop the lock open and then pull the door open. Rekeying Rekeying is the procedure of changing a lock's pin combination in a cylinder so that only new keys can unlock it. It's less expensive and less time-consuming than replacing the lock. It also provides more security. It's also among the most simple locksmith jobs for home use to complete. Most door locks are operated by keys.

Additionally, it can also provide security for homeowners who recently moved into a new home. An electric power lock uses magnetic fields or motors that are activated by electric currents to move the door handle. The electric system can fail due to a variety of reasons: the remote's battery could be damaged, the wiring may have been damaged by the elements or a break-in or it could have been unable to function without a reason.
