Car remotes are a 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 times.

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

Keyless Entry System

Instead of having to fiddle around with keys in your pocket or purse instead, stroll up to your car, press an icon on the key fob and then unlock the doors and start the engine. It's a useful feature that has made the experience of car driving more enjoyable and safer. However, just like any other device, the keyless entry system could break from frequent use or due to other reasons. If you've encountered issues with yours, you have two options: Go to the dealership or contact the local locksmith.

The way a keyless entry system operates is by releasing radio signals, and then searching for a corresponding response signal from the key fob. If the system recognizes the signal, it triggers to unlock the car doors and also activate the computer onboard. Certain systems have another receiver mounted on the car's trunk that will open automatically when you move your foot under it.

Each key fob is equipped with an unique digital identification code that is issued by the manufacturer. A unique process of technology known as "programming" is used to make sure that the fob is set up to work with the specific car's system. This usually involves turning on the car's ignition multiple times in a particular sequence and may also involve pushing or pulling different buttons and levers, or taking out fuse.

When a key fob key repair is programmed to your vehicle's keyless entry system it transmits its digital identification code as well as a function code that tells the car what to do (lock in, unlock, or open the trunk). The receiver on the car verifies the transmitter's identity through an authentication and encryption process. The computer on board will allow the vehicle to be opened and start the engine if it's authenticated.

There are fears that a criminal with a sly approach could intercept the code transmitted between the key fob and the car. This would require a special device to record the transmission and then retransmit it in the event that the system doesn't anticipate it. To prevent this from happening issue, the majority of keyless entry systems use rolling code that ensures that every new signal from the transmitter received by the vehicle has a different counter value than the previous one.

Batteries

A dead battery is the main reason for car remotes not to function. It's a cheap and easy fix when you have an extra key fob on hand to replace the old one with. Most fobs are powered with watches-style batteries, which are available at big-box stores or hardware stores for less than $10. A quick search on the internet or your car key repair's owner's manual will provide directions on how to disassemble your key fob and replace the battery.

After you've removed your battery, be careful not to disturb any of the circuits or antennas in the case. They are likely holding the key fob's program to your particular car, and messing with them will make it impossible to program (and likely to fail). If you must move them, do it very gently because some key fobs have fasteners that are able to open and scatter key fob pieces all over your living room.

The case of a majority of key fobs has one screwdriver hole. To open it, you can make use of a pry tool. But, to start, wedge the pry tool around the outer edge of the case as you would when peeling an orange or apple. Do not apply too much pressure, as the fob case is often made of plastic and can break or crack if apply too excessive force to it.

If you're ready to replace the battery, be sure to match the size and type to your key fob. Some key fobs come with two batteries while others require one. The wrong battery can render your remote keyfob useless.

If the issue persists then you can try it again with your fob's key after installing the new battery. If this doesn't work you'll have to determine if the fob is suffering from a more complex issue that requires professional diagnosis. If this is the case, you could require it to be changed by a dealer or purchase a new key fob entirely.

Buttons

The buttons on your key fob are small, and they're packed with delicate electronics. Therefore, it's not surprising that they're destined to fail from time time. The good news is that if your car key button isn't working, there's usually something you can do to fix it yourself.

The most frequent reason why that a car remote stop functioning is due to dirt or crud has been trapped between the button. To clear this up take care to remove both batteries and clean each button using a cotton swab that has been coated with ruby alcohol. Be sure to dry the buttons completely before reinstalling them.

It's possible that your key fob is damaged in any way, for example, being dropped on concrete or accidentally scratched. If this is the situation, you can check the function of your key fob using a different one.

The door lock sensor might have stopped working in your car. 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 prolonged usage or exposure to harsh weather conditions. Press your key button several times without locking or unlocking your doors. This resets the sensor.

If all else fails, you could always check the functioning of an extra key fob repair service by trying to lock and unlock your doors with it. If the spare key does not work, it might be necessary to locate an emergency locksmith who can provide automobile key repair in order to make your remote work again.

If your car key button is working but still not locking or unlocking the vehicle, try reprogramming your computer system. If you've had the same key fob a time, it may need to be reset every few months in order to to work with your vehicle. It's not optimal, but it's better than having to purchase an entirely new remote.
