Car Key Repair - How to Fix a Dead Remote

The car remotes are a wonderful convenience for drivers. They can unlock doors, access trunks, and even start the engine. However, they may stop working at odd times.

Before you head to the dealer, try some quick fixes when your key fob stops working. These steps could save you money.


Keyless Entry System

Instead of fumbling around with keys in your pocket or purse instead, walk up to your car, press a button on the key fob, then unlock the doors and start the engine. It's a convenient feature that has made the world of car driving more enjoyable and more secure. However, just like any other device that has a keyless entry system, the keyless entry system could break from repeated use or due to other factors. If you've experienced problems with your keyless entry system, there are two options: visit 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 from the key fob. If remote car key repair recognizes the signal, it's triggered to unlock the vehicle doors and also activate the computer onboard. Certain systems have another transmitter located in the trunk of the car that opens when you move a foot under it.

Each key fob is given a unique digital identification code by the manufacturer. The fob is programmed by an exclusive process known as "programming". This involves turning the ignition of the vehicle repeatedly in a predetermined sequence, and may also require pulling buttons or levers, or even removing the fuse.

Once a key fob is programmed to the car's keyless entry system it transmits its digital identity code as well as a function code that instructs the car what to do (lock or unlock the trunk, or open the trunk). The car's receiver verifies the transmitter's identity through an authentication and encryption process. The onboard computer will unlock the vehicle and start the engine when it is authenticated.

A savvy criminal could steal and use the code sent between the keyfob's and the vehicle. This would require a device to record the transmission and then transmit it again when the system isn't expecting it. To prevent this from happening, most keyless entry systems rely on a method called rolling code that guarantees that each new transmitter signal received by the vehicle has a different counter value than the previous one.

Batteries

The most frequent cause of car remotes key fobs not working is the battery is dead. It's a simple and inexpensive fix in the event that you have a spare key fob on your desk to replace the old one with. Luckily, most fobs use standard watch-style batteries that can be purchased in hardware stores or big-box retailers for as little as $10. You can find directions to disassemble your key fob on the internet or in your vehicle's manual.

Be careful not to harm any circuits or antennas inside the case after you've removed the battery. They're likely to hold the key fob's program to your particular car, and messing with them will render it impossible to program (and likely to fail). If you have to move them, do it very gently because some key fobs come with fasteners that are able to open and scatter key fob parts across your living room.

Most key fobs have one hole that can be used with an screwdriver or similar tool to pop open the case. However, it's a good idea to put your tool on the outside of the case first, like you were peeling an apple or orange. Be careful not to apply too much pressure since the case of the key fob is generally made of plastic, and is susceptible to breaking or cracking when you apply too the force.

When you're ready to replace the battery, be sure to match its size and type to the key fob. Some key fobs require two batteries, whereas others only have one. Using the wrong battery can quickly make your remote key fob useless.

If the problem persists then you can try it 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 a professional diagnosis and repair. You may have to have your key fob reprogrammed at an authorized dealer or purchase an entirely new one.

Buttons

The tiny buttons on your key fob are tiny, and filled with delicate electronics. It's not a surprise that they'll fail from time-to-time. If your car key button suddenly ceases to function, you can generally fix it yourself.

The most common reason the car remote stops working is due to dirt or crud have trapped between the buttons. To clear this up remove the batteries and clean each button with a cotton swab that has been dipped in ruby alcohol. Make sure to dry them thoroughly before reinstalling 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 the case, using another key fob to check its functionality may reveal that yours has been damaged and has to be replaced.

Another possibility is that the door sensor for your car's lock isn't working anymore. It's a tiny metal piece that is attached to the door lock button on your key fob and it's not common for this sensor to break after long-term usage or exposure to harsh weather conditions. Press your key button a few times without locking or unlocking your doors. This resets the sensor.

If all else fails you can always test the functionality of a spare key by unlocking and locking your doors with it. If the spare key does not work, it could be necessary to locate an 24 hour locksmith that can offer auto key repair to get your remote working again.

You can reprogram your computer if your car's key button works however it cannot lock or unlock your vehicle. If you've used the same key fob for a time, it may need to be reprogrammed every few months to continue to work with your vehicle. It's not optimal, but it's better than having to purchase an entirely new remote.
