Car Key Repair - How to Fix a Dead Remote
Car remotes are a great convenience for drivers. They can unlock doors, open trunks, and even start the car. However, they may stop working at inconvenient times.
Before you go to the dealer, you can try a few quick solutions when your key fob stops functioning. These steps could save you money.
Keyless Entry System
There's no need to search for keys in your purse or pockets. Just walk to car key repair , push the button on the keyfob and the doors will open and the engine will get started. It's a useful feature that has made the experience of car driving more comfortable and more secure. The keyless entry system, as any other device, could be damaged by repeated use or other elements. If you've experienced problems with yours, you have two options: visit the dealership or call an emergency locksmith in your area.
The way that a keyless entry system functions is by sending radio signals and then searching for a corresponding response signal from the key fob. If the system recognizes the signal, it triggers to open the doors of the vehicle and also activate the computer onboard. Certain systems have a second receiver on the trunk of the car, which opens automatically when you waggle your foot under it.
Each key fob has an unique digital identification code that is issued by the manufacturer. The fob is programmed with an exclusive process known as "programming". This usually involves turning the ignition of the car multiple times in a particular sequence, and could include pulling or pushing various buttons and levers or taking out fuse.
Once a key fob has been programmed to your vehicle's keyless entry system it transmits its digital identification code, along with a function code that instructs the car what to do (lock in, unlock, or open the trunk). The car's receiver confirms that the transmitter is who it claims to be using an authentication and encryption procedure. If it's authorized, the onboard computer unlocks the vehicle and then starts the engine.
A savvy criminal could steal and use the code transmitted between the keyfob and vehicle. This will require an instrument 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 prevent this. This ensures that each new transmitter signal received by a vehicle has a counter value that is different from the previous one.
Batteries
The most frequent reason for car remotes key fobs not working is the battery is dead. If you have an extra key fob it's a cheap and easy fix. Most fobs are powered with watches-style batteries, which can be purchased at hardware stores or big-box 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 take apart your key fob and replace the battery.
Be careful not to damage any of the circuits or antennas within the case after you've removed your battery. If you make a mess of them the key fob could be unprogrammable and won't work. If you must move them, do it with care as some key fobs have fasteners that are able to open and scatter key fob pieces all over your living room.
The majority of 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 put your tool on the outside of the case first, just as you would peeling an apple or orange. Don't apply too much pressure, since the fob case is often made of plastic and may break or crack if apply too much pressure to it.
If you're ready to replace the battery, be sure to match the size and type to your key fob. Some fobs require two batteries, whereas others only have one. Using the wrong battery can quickly render your remote key fob ineffective.
After the new battery has been put in place, test your key fob for the second time to see if it solves your issue. If it doesn't then you'll need to figure out if your fob has a more complicated issue that requires a professional diagnosis and repair. You may need to have your key fob reprogrammed by the dealer or purchase a new one.
Buttons
The buttons on your key fob may be small, but they are packed with electronic components. It's not surprising that they'll malfunction from time to time. The good thing is, when your car's key button isn't working, there's usually something you can do to fix it yourself.
One of the main reasons a car key remote stops working is due to dirt or dust that has become lodged between the buttons. To remove this obstruction take care to remove both batteries and scrub each button using a cotton swab that has been dipped in alcohol rubbing. Make sure to dry them thoroughly before installing the batteries.
It's possible that the key fob was harmed in some way, possibly dropped on concrete or unintentionally damaged by something sharp. If this is the case using an alternative key fob to test 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 connected to the key fob's door lock button. It's not common for it to fail due to weather conditions or extended use. To reset the sensor simply press your key button several times without locking or unlocking your doors to reset it.
If all other options fail, you can always test the operation of a spare key by trying to unlock and lock your doors using it. If the spare key does not work, you may have 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 it's still not locking or unlocking your vehicle, try to reprogram your computer system. However, keep in mind that if you've used the same key fob for some time, it will have to be programmed every couple of months to ensure it continues to work properly with your vehicle. It's not the most ideal solution, but it's better than buying a new remote.
