It is recommended to speak with a professional auto locksmith.
Unlocking the Door
Getting locked out of the car is a frustrating experience, but there are several options to get back inside. If you are covered by roadside assistance with AAA or another company, they can send a locksmith to you, but you may also be able to get back into your car using DIY tools and techniques. These methods work best with cars that have power door locks, which can be opened by pressing the lock button on the armrest or using the keychain.
To make this method work you'll need a wire hanger, which is straightened out and turned into a hook at one end, or other long, rigid tool that won't be able to bend under pressure. G28 will need to be long enough to reach the door handle or the lock button, and should include a hook on one end to catch the latch inside the door. You will also need tools like pliers to secure the hanger's ends and a pair of long tweezers to move it.
First, you'll need to create a space between the window frame and the body. Then, slide the rod or hook from the hanger into the opening you have created and then try to slide or press the door lock flipper or button using it. The door should then open with a bit of luck.
If your car is equipped with an electronic lock, you'll have to figure out a way to open the door from the inside without knowing the code. You can pull a lever located on the inside of the door to unlock it, but first you need to know how to access it. You can employ the Slim Jim or another long tool to reach the lever.
In certain situations, none of the options above are effective and you'll have to call an expert locksmith for help. If that's the case, be sure to ask them what the cost will be before they show up.
Unblocking the Keyhole
If the lock is jammed due to the key was not fully engaged then gently push the pin tumblers back into the correct alignment inside the internal cylinder. It may solve the problem However, pushing too hard can cause more damage. In this case it is recommended to seek out a locksmith.
Keep the lock lubricated with graphite spray, or a silicone based product. They are superior to oils-based products, like WD-40, which are more likely to attract dirt and debris. Apply the product to the lock, insert and turn the key several times, then move the key around into the hole to distribute the lubricant across the mechanism.
Powdered graphite is a different item that you should keep in your toolbox. It functions as a dry oil lubricant. It encourages smooth movement between metal surfaces, without being a magnet for grime or dirt and is safe to use on locks that have internal pin tumblers. Try applying a few grains of the powder inside the lock to lubricate it and remove any gunk that may have been accumulating in the keyhole.
It is also essential to replace your key on a regular basis to ensure it's in good shape and also to prevent it from jamming over time. This will allow it to last longer and perform more efficiently.
If the key still isn't turning freely or is prone to jamming it could be worn out and require replacement or a key recut. To avoid sticking in the future, you can apply a file to the sharp edges of the key teeth. But, this is a job that should be left to professionals.
If the above suggestions don't work, you can attempt to remove the stuck key by taking the strike plate out of the door frame, and then filing down the lower lip of the plate to increase the size of the opening in where the key is placed. If this fails, it's best to call a locksmith who has the tools needed to disassemble a car door and fix the problem. They'll have specialized tools designed to enter the locking mechanisms to detach them. They will also be able to identify the reason the lock isn't working properly.
Unfreezing the Lock
Locks that freeze are common during the Polar Vortex, which brings cold temperatures and winter storms. There are a few quick methods you can use to defrost the lock and then open your vehicle. The first step is to chip away any large chunks of ice that are preventing the lock cylinder from accepting the key. To avoid damaging the cylinder of the lock or the car door, it is crucial to be careful in this process.
Pouring boiling water on the lock is another common trick. Although this may work for a short time but it could damage your lock over the long haul and likely re-freeze any moisture that is still in the lock cylinder. Pouring hot water into the lock or door sensor could cause the door sensor to experience a thermal shock. You could also harm the car lock or door with sharp or metal objects.
An alternative is to heat the key with match or lighter and then insert it into the lock. Heating the key using a lighter or a hair dryer will create enough heat to melt away the ice that's encased the lock cylinder, making it easier to insert the key and open the door. If you're unable to insert the key all the way into the lock, warm it again and try again. You can get rid of ice from your lock by spraying a grease on the lock, or using a commercial de-icer.
It is a great idea to leave your car parked in the sun, and let the sun to melt the lock. This can take a while to accomplish, but it's an easy and affordable solution to a locked that is frozen issue. It is recommended to keep an empty can of de-icer in your bag for times of need. The chemicals will break down the ice and prevent further freezing.
Replacing the Actuator
The actuator is a tiny motor that moves the lock using a set of gears. It can be activated using keys in the door or a remote control or keyless entry, or a central control. It is a very low-power device which can be worn out over time. When it does wear out it will create a buzzing or machine gun sound that will not stop until the actuator is replaced.
Replacing the actuator is a simple task for most people with a few tools and a bit of perseverance. The steps might differ among different vehicles since manufacturers put the components together differently however the fundamental procedure is the same. First disconnect the battery to avoid electrical issues from occurring during the repair. After that, remove the door panel from the. Depending on the vehicle, you may also need to remove the window and/or regulator in order to gain access to the actuator.
When you remove the panel, you can see the actuator that is attached to the door latch. Usually the bolts that hold the actuator in place can be removed with the aid of a screwdriver. The actuator can then be removed from its mount. After the new one is in place, reinstall the connector that goes to the wiring harness. Reconnect the cables and rods to the latch, actuator and door panel.
When the trim panel is reinstalled, you should replace any clips that were removed during removal. Make sure to check all screws to make sure they are securely tightened. This will prevent any looseness or rattle. Reconnect all wires disconnected and test the actuator to confirm it is working. Reinstall the door panel, trim piece, and battery. Then, conduct another test. If your doors aren't functioning as they should, it might be time to replace your actuator.
