Car Key Repair - How to Fix a Dead Remote

The car remotes are a wonderful convenience for drivers. They can unlock doors, open trunks, and even start the engine. However, they can cease to function at uninviable times.

If you find that your key fob is not working, you can try a few fixes before going to the dealership. These tips could save you money.

Keyless Entry System

Instead of having to fiddle around with keys in your purse or pocket Instead of fumbling around with keys in your purse or pocket, you can walk up to your car, hit a button on the key fob, and then open the doors and start the engine. It's a practical feature that has made the world of car driving more comfortable and safer. But, like all devices it's possible that the keyless entry system can be damaged by repeated use or because of other factors. If you've had issues with yours, there are two options: Go to the dealer or contact an emergency locksmith in your area.

The way a keyless entry system operates is by sending out radio signals and then searching for a corresponding response signal from the key fob. If the system detects the signal, the vehicle's doors are opened and the onboard computer activated. Certain systems have a second transmitter on the trunk of the car which opens it when you waggle a foot under it.

Each key fob has a unique digital identification code that is given by the manufacturer. A unique process of technology known as "programming" is used to configure the fob with a specific car's system. This typically involves turning the ignition of the car repeatedly in a specific sequence. It could include pulling or pushing various levers and buttons or the removal of fuses.

Once the key fob is programmed into your car's keyless system it transmits a digital identity code as well as a function-code to instruct the car on what to do (lock the trunk, unlock it or open the trunk). The car's receiver confirms the identity of the transmitter through an authentication and encryption process. The computer in the car will unlock the vehicle and start the engine if it is authenticated.

A clever criminal could intercept and use the code sent between the keyfob's and the vehicle. This would require the use of a device that records the transmission, and then transmits it again in the event that the system doesn't want it. Most keyless entry systems utilize rolling codes to combat this. This ensures that every new transmission signal received by a vehicle has a counter that is different from the previous one.

Batteries

A dead battery is the most frequent reason for the car remote to not function. It's a cheap and easy fix if you have a spare key fob on hand to replace the old one with. Most fobs are powered by watches-style batteries, which can be purchased at big-box stores or hardware stores for less than $10. A quick search of the internet or in your vehicle's owner's manual should give you instructions on how to disassemble the fob that you have been using and replace the battery.

Be careful not to damage any antennas or circuits in the case once you've removed the battery. They are likely holding the key fob's program to your specific car and any disruption to them will make it impossible to program (and probably not work). If you must move them, do so with care, as some key fobs come with fasteners that easily open and scatter key fob pieces all over your living room.

The case of the majority of key fobs has a single screwdriver hole. To open it, you'll need to use a tool to pry it open. To begin, wedge the pry tool around the outer edge of the case as you would peel an apple or orange. Be careful not to 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 exert too excessive force.

If you're ready to replace the battery, be sure to match its size and style to your key fob. 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 once more to see if the battery has fixed your problem. If this fails then you'll need to determine whether your fob is experiencing a more complex issue that requires a professional diagnosis. If this is the case, you might need to have it changed by a dealer or you may need to buy a replacement key fob altogether.

Buttons

The buttons on your key fob might appear small, but they are packed with electronics. It's not a surprise that they're destined to fail from time time. If your car key button suddenly stops working, you can typically fix it yourself.

The most common reason that a car remote stop working is due to dirt or crud has been lodged between the buttons. To remove this obstruction, carefully remove both the batteries and scrub each button by using a cotton swab, coated with alcohol rubbing. Be sure to dry them completely before replacing the batteries.

It's possible that your key fob was damaged in any way, for example, being dropped on concrete or accidentally scratched. If that's broken car key repair , using another key fob to test its functionality might reveal that it has been damaged and has to be replaced.

The door lock sensor may have stopped working in your car. The sensor is a tiny metal part that is attached to the key fob's door lock button. It's not common for it to fail due to weather conditions or prolonged use. To reset the sensor simply press your key fob a few times without locking or unlocking your doors to reset it.

If all else fails, you can always check the functioning of a spare key by trying to unlock and lock your doors with it. If broken car key repair does not work, you may have to contact a locksmith on call 24 hours a day who offers automobile key repair to make your remote work again.

You can reprogram your computer if your car key button is working but doesn't lock or unlock the vehicle.

It's not the most ideal solution, but it's better than buying an entirely new remote.
