Car Key Repair - How to Fix a Dead Remote
Car remotes provide a great convenience to drivers. They can unlock doors, access trunks and even start the engine. However, they may stop working at inconvenient times.
Before you head to the dealer, try some quick solutions when your key fob stops working. These suggestions could save you money.
Keyless Entry System
You don't have to look for keys in your pockets or purse. Simply walk up to your car, push the button on the keyfob, and the doors will be opened and the engine will begin. It's an easy feature that makes driving a car more relaxing and safe. The keyless entry system, just like any other device, can be damaged through repeated use or other factors. If you are having issues with your system, you can either visit the dealer or phone a locksmith.
Keyless entry systems operate by sending radio signals and then scouring for the response signal from a key fob. If the system detects the signal, the vehicle's doors are opened and the onboard computer activated. Some systems have an additional receiver in the car's trunk that will open automatically when you put your foot under it.
Each key fob has a unique digital identity code that's given by the manufacturer. A specific process of technology called "programming" is used to set the fob up to work with the specific car's system. This requires turning the ignition of the vehicle repeatedly in a certain sequence, and could require pushing or pulling buttons or levers or levers or removing the fuse.
Once the key fob is programmed into your car's keyless system, it transmits a digital identification code as well as a function-code to instruct the car on what to do (lock or unlock the trunk). The receiver in the car verifies that the transmitter is the person it claims to be by using an authentication and encryption procedure. The computer on board will unlock the vehicle and start the engine if it's authorized.
A clever criminal could intercept and use the code sent between the keyfob and vehicle. This would require a specific device to record the transmission and then retransmit it when the system isn't expecting it. The majority of keyless entry systems employ a rolling code method to stop this. This ensures that each new transmitter signal received by a car has a counter value that differs from the previous one.
Batteries
The most frequent cause of the 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. The majority of fobs are powered by watch-style batteries that are available at hardware stores or big-box stores for less than $10. You can find the steps to disassemble your key fob by searching the web or in your vehicle's manual.
After you've removed your battery, make sure not to disrupt any of the circuits or antennas in the case. They're likely to be holding the key fob's programming to your specific car and any disruption to them will make it unprogrammable (and probably not work). If you need to move key fobs, be careful. Certain key fobs might have fasteners which can easily open and scatter key fob pieces all over your living space.
The case of a majority of key fobs has a single screwdriver hole. To open repair car keys , use a pry tool. To begin you must push the tool around the outer edge of the case, just as you would do when peeling an apple or orange. Do not apply too much pressure as the case of the key fob is usually constructed of plastic and it is prone to break or crack when you apply too excessive force.
Make sure you match the size and type of the battery to the key fob when replacing it. Some key fobs have two batteries while others only need one. The wrong battery could make your remote key fob useless.
If the problem persists it is possible to try again with your fob's key after installing the new battery. If it doesn't work you'll have to determine if the fob is suffering from an issue that is more complicated and requires a specialist diagnosis. It could be necessary to have your key fob reprogrammed at the dealer or purchase a new one.
Buttons
The tiny buttons on your key fob are pretty small, and they're packed with delicate electronics. So it's not too surprising that they're destined to fail from time to time. If your car key button suddenly stops working, you can usually fix it yourself.
One of the main reasons why a car key remote doesn't work is because dirt or grit has accumulated between the buttons. To remove this obstruction take care to remove both batteries and clean each button using a cotton swab that has been dipped in rubbing alcohol. Make sure you dry the buttons completely before reinstalling them.
It's possible that your key fob was damaged in some way, like being dropped on concrete or accidentally scratched. If this is the situation, you can check your key fob's functionality by using another one.
Another possibility is that the door sensor for your car's lock has stopped working. It's a tiny metal part that is attached to the key fob's door lock button. It is not uncommon for it to break due to weather conditions or prolonged usage. Press your key button several times without locking or unlocking your doors. This resets the sensor.
If all else fails, you can always check the functioning of the spare key by attempting to lock and unlock your doors with it. If the spare key does not work, you may have to contact a locksmith on call 24 hours a day who offers automobile key repair to get your remote working again.
You can reprogram your computer if your car's key button works however it does not lock or unlock the vehicle. Be aware that if you've owned the same key fob for a long time, it's going to need to be programmed each few months to ensure that it remains in sync with your vehicle. It's not the most ideal solution, but it's better than buying another remote.
