remote car Key RepairCar remotes provide a excellent convenience for drivers. They can unlock doors, open trunks and even start the engine. But, these remotes sometimes cease to function at uninviable times.
If you notice that your key fob is no longer working, try a few fixes before heading to the dealer. These tips could save you money.
Keyless Entry System
You don't need to search for keys in your purse or pockets. Just walk up to your car, press the button on the keyfob and the doors will be opened and the engine will begin. It's a simple feature that makes driving a car more enjoyable and safe. The keyless entry system, just like any other device, could be damaged by repeated use or by other factors. If you're having problems with yours, you may either visit the dealer or phone a locksmith.
The way a keyless entry system operates is by sending out radio signals, and then searching for a response signal from the key fob. If the system detects the signal, the car's doors are unlocked and the computer on board is activated. Certain systems have another receiver mounted on the trunk of the car that will open automatically when you waggle your foot under it.
Each
automotive key repair fob is equipped with a unique digital identification code, which is assigned by the manufacturer. A specific process of technology called "programming" is used to set the fob up with the car's specific system. This usually involves turning the ignition of the vehicle several times in a certain sequence and may include pulling or pushing various buttons and levers or the removal of fuses.
Once a key fob has been programmed into your car's keyless system, it transmits a digital identification code and a function code that instruct the car to (lock, unlock or open the trunk). The receiver on the car verifies the transmitter's identity through an authentication and encryption process. If it is authorized, the computer on board unlocks the vehicle and begins the engine.
There are concerns that a skilled criminal could intercept the code that's transmitted between the key fob and the car. This will require a device that records the transmission, and then retransmits it when the system doesn't expect it to. To prevent this from happening, most keyless entry systems rely on the rolling code method that guarantees that each new transmitter signal received by the vehicle has a different counter than the previous one.
Batteries
The most common cause of a car remote key fob not working is the battery is dead. If you have an extra key fob it's a cheap and easy fix. Luckily, most fobs use traditional watch-style batteries which can be purchased in hardware stores or big-box retailers for as little as $10. You can find the steps to disassemble the key fob on the internet or in your vehicle's manual.
After you've removed your battery, be careful not to damage any circuits or antennas inside the case. If you do this the key fob will become unprogrammable and will not function. If you must move them, do so slowly because certain key fobs have fasteners that are able to pop open and scatter key fob components throughout your living space.
The case of most
key repair car fobs has one screwdriver hole. To open it, use a tool to pry it open. To begin you must push the tool along the outside edge of the case, just as you would do when peeling an apple or orange. Do not apply too much pressure since the case of the key fob is usually made of plastic, and it is prone to break or crack with too the force.
When you're ready for replacing the battery, make sure to match the size and type to your
automotive key repair fob. Some fobs require two batteries, whereas others have only one. The wrong battery can render your remote key fob ineffective.
If the problem persists, you can try again with your fob's key after installing the new battery. If not it, you'll have to determine if your fob has a more complicated issue that requires professional diagnosis and repair. If this is the case, you may require it to be reprogrammed by a dealer, or purchase a replacement key fob completely.
Buttons
The buttons on your key fob might appear small however they're packed with electronics. It's not a surprise that they're likely to fail from time to time. If the button on your car's ignition suddenly stops working, you'll be able to usually fix it yourself.
One of the most frequent reasons why a car key remote stops working is that dirt or crud has become lodged between the buttons. To remedy this, take out the batteries carefully and clean each button using a cotton swab that has been submerged in the rubbing alcohol. Be sure to dry them completely before installing the batteries.
It's possible that the key fob was damaged somehow, perhaps dropped on concrete, or perhaps damaged by something sharp. If that's the case, using a different key fob to verify its function could reveal that the one you have been damaged and requires to be replaced.
The door lock sensor might have stopped working in your car. This is a tiny metal part that's connected to the door lock button on your key fob and it's not uncommon for this sensor to break following long-term use or exposure to weather conditions. To activate the sensor again, simply try pressing your key button a few times without locking or unlocking your doors to reset it.
If nothing else works, you can always test the function of a spare key by opening and locking your doors with it. If the spare key doesn't work, you may have to call a locksmith 24 hours a day who can repair your car keys to get your remote working again.
If the car key button is working, but it's still not locking or unlocking the vehicle, try to re-programme your computer system. But keep in mind that if you've used the same key fob for some time, it's likely to need to be programmed every couple of months to ensure that it continues to work properly with your vehicle. It's not optimal, but it's better than having to buy a new remote.
