Car Key Repair - How to Fix a Dead Remote
Car remotes offer great convenience to drivers. They can unlock doors, open trunks and even start the car. Remotes that work with these remotes may stop working at the most inconvenient of instances.
Before you visit the dealer, consider some quick solutions if your key fob stops functioning. These suggestions could save you money.
Keyless Entry System
Rather than needing to fumble around with keys in your pocket or purse Instead of fumbling around with keys in your purse or pocket, you can walk to your car, push an icon on the key fob and then unlock the doors and start the engine. It's a convenient feature that has made the experience of car driving more comfortable and safer. The keyless entry system, just like any other device, may be damaged by repeated use or by other causes. If you have problems with yours, you can either go to the dealer or contact a locksmith.
The way that a keyless entry system functions is by sending out radio signals and then looking for a response signal from the key fob. If the system is able to recognize the signal, the vehicle's doors are opened and the onboard computer is activated. Some systems include an additional receiver in the trunk of the car, which opens automatically when you put your foot underneath it.
Each key fob is given a unique digital identification code by the manufacturer. The fob is programmed by a proprietary process called "programming". This usually involves turning on the car's ignition repeatedly in a specific sequence, and could include pulling or pushing various levers and buttons or taking out fuses.
Once a key fob has been programmed into your car's keyless system it transmits a digital identification code as well as a function-code to instruct the car to (lock, unlock or open the trunk). The car's receiver verifies that the transmitter is the person it claims to be using an authentication and encryption process. If it is authorized, the computer on board unlocks the vehicle and begins the engine.
A savvy criminal could steal and use the code transmitted between the keyfob and the vehicle. This would require the use of an instrument that records the transmission and then retransmits it later when the system doesn't expect it to. To combat this issue, the majority of 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
A dead battery is the most common reason for the car remote to not work. If you have an extra key fob, it's a low-cost and simple fix. Luckily, most fobs use regular watch-style batteries that are available in hardware stores or big-box retailers for less than $10. You can find the steps to disassemble your key fob on the web or in your vehicle's manual.
After you've removed the battery, be sure not to damage any circuits or antennas inside the case. They're likely to hold the key fob's program to your specific car and tampering with them can cause it to become impossible to program (and likely to fail). If you must move the key fobs, take care. Certain key fobs might have fasteners that can easily pop out and scatter key fob pieces all over your living space.
Most key fobs come with one hole that allows the screwdriver or another pry tool to open the case. However, it's a good idea to use your tool to wedge it around the outside of the case first, just as you would peeling an orange or apple. Don't apply too much pressure as the case of the key fob is generally made of plastic, and it is prone to break or crack with too much force.
Be sure to match the size and type of battery to your key fob when replacing it. Some key fobs come with two batteries, while others only need one. The wrong battery can cause your remote to become useless.
Once the new battery is installed, test your key fob again to see if the battery has fixed the issue. If key fob repairs , you'll have to determine whether your key fob is suffering from an issue that's more complex that requires a professional diagnosis and repair. If this is the case, you might require it to be changed by a dealer or buy a replacement key fob entirely.
Buttons
The buttons on your key fob may be small but they're loaded with electronics. It's not a surprise that they will malfunction from time to time. The good news is that when your car's key button stops functioning, there's usually something you can do to fix it yourself.
One of the main reasons why a car key remote doesn't work is due to dirt or dust that has become lodged between the buttons. To remove this obstruction, carefully remove both the batteries and clean each button with a cotton swab coated with rubbing alcohol. Make sure to dry them completely before replacing the batteries.
It's also possible that the key fob has been damaged by accident, such as being dropped on concrete or accidentally damaged by something sharp. If that's the case, using a different key fob to verify its function may reveal that yours has simply been damaged and needs to be replaced.
car key fob repairs could have stopped working in your vehicle. It's a tiny, metal component that's attached to the door lock button on your key fob and it's not unusual for the sensor to break following long-term use or exposure to weather conditions. Press your key button several times without locking or unlocking your doors. This will reset the sensor.
If all else fails, you can test the capabilities of a spare key by opening and locking your doors using it. If the spare key doesn't work, you might need to call a locksmith 24 hours a day who provides repair of car keys to make your remote work again.
If the car key button is working but still not locking or unlocking the vehicle, try to reprogram your computer system. If you've had the same key fob for a while, it may need to be reset every few months to continue to work with your vehicle. It's not the ideal situation however it's much better than having to replace your remote entirely.
