Car Key Repair - How to Fix a Dead Remote
Car remotes are an excellent convenience for drivers. They allow you to unlock doors, gain access to trunks and even start the engine. These remotes are prone to malfunction at the most inconvenient moments.
If you discover that your key fob no longer working, try a few simple fixes before heading to the dealer. These tips could save you money.
Keyless Entry System
You don't need to search for keys in your purse or pockets. Simply walk up to remote key fob repair near me , press the button on the keyfob, and the doors will be opened and the engine will get started. It's a simple feature that makes driving a car more comfortable and safe. But, like all devices it's possible that the keyless entry system can be damaged by repeated use or because of other reasons. If you have problems with yours, you may either go to the dealer or contact an locksmith.
A keyless entry system operates by sending radio signals, and then looking for a response signal from a key fob. If the system detects the signal, the car's doors are unlocked and the computer on board is activated. Certain systems have a second receiver on the car's trunk that will open automatically when you move your foot underneath it.
Each key fob is assigned an unique identification code by the manufacturer. The fob is programmed with a proprietary process called "programming". This usually involves turning the ignition of the vehicle several times in a certain sequence and may include pulling or pushing various buttons and levers or taking out fuses.
When a key fob is programmed to your specific vehicle's keyless entry system it transmits its digital identity code as well as an operation code that tells the car what to do (lock or unlock the trunk, or open the trunk). The car's receiver checks the authenticity of the transmitter by an authentication and encryption process. If it's authorized the onboard computer unlocks vehicle and starts the engine.
A savvy criminal could steal and then use the code that is transmitted between the keyfob's and the vehicle. This would require the use of a device that records the transmission and then retransmits it when the system doesn't anticipate it to. Most keyless entry systems use the rolling code method to combat this. This ensures that every new signal from a transmitter received by a car has a counter that is different from the previous one.
Batteries
The most common cause of a car remote key fob not working is an inoperative battery. It's a simple and inexpensive fix in the event that you have another key fob at your desk to replace the old one with. Luckily, most fobs use regular watch-style batteries that can be purchased in hardware stores or big-box retailers for $10 or less. A quick search on the internet or your car's owner manual should provide instructions on how to take apart your key fob and replace the battery.
Be careful not to harm any circuits or antennas inside the case after you've removed your battery. They are likely holding the key fob's programming to your car's specific model, and messing with them will make it unprogrammable (and likely to fail). If you have to move them, do it very gently, as certain key fobs have fasteners that easily pop open and scatter key fob components across your living room.
Most key fobs have one hole that can be used with the screwdriver or another pry tool to open the case, however it's best to use your tool to wedge it around the outside of the case first, like you would peeling an orange or apple. Be careful not to apply too much pressure, since the fob case is often constructed of plastic and could break or crack if apply too excessive force to it.
Be sure to match the size and style of the battery to the key fob when you replace it. Certain fobs require two batteries, whereas others have just one, and the wrong battery can render your remote key fob useless.
After the new battery has been put in place, try using your key fob for the second time to see if it solves the issue. If not, you'll need to determine whether your device has a more complicated issue that requires a professional diagnosis and repair. You may have to have the key fob reprogrammed at the dealer or purchase another one.
Buttons
The buttons on your key fob might be tiny however they're packed with electronic components. It's not a surprise that they'll fail from time-to-time. The good thing is, in the event that your car's keypad isn't working, there's usually something you can do to fix it yourself.
One of the most frequent reasons why a car key remote doesn't work is because dirt or grit has accumulated between the buttons. To get rid of this, carefully remove both the batteries and clean each button with a cotton swab that has been dipped in ruby alcohol. Be sure to dry them completely before installing the batteries.
It's also possible that the key fob was damaged by accident, such as being dropped on concrete, or perhaps scratched by something sharp. If this is the case, using a different key fob to test its functionality might reveal that it has simply been damaged and needs to be replaced.
Another possibility is that the door lock sensor in your vehicle has stopped working. This sensor is a small metal component attached to the key fob's door lock button. It is not common for it to fail due to weather conditions or long usage. Press your key button several times without locking or unlocking your doors. This resets the sensor.
If all else fails, you can always test the function of a spare key by opening and locking your doors with it. If the spare key doesn't work, you might need to contact a 24-hour locksmith who offers automobile key repair to make your remote work again.
You can reprogram your computer if your car's key button works but doesn't lock or unlock the vehicle. Be aware that if you've used the same key fob for some time, it will have to be programmed every couple of months to ensure that it continues to work properly with your vehicle. It's not the ideal situation, but it's better than having to replace the remote completely.
