These suggestions could save you money.<br /><br />Keyless Entry System<br /><br />Instead of having to fiddle around with keys in your pocket or purse, you can simply walk up to your car, push an icon on the key fob, then unlock the doors and start the engine. It's a practical feature that has made the experience of car driving more enjoyable and more secure. But, like all devices, the keyless entry system could break from repeated use or due to other reasons. If you're having problems with yours, you may either visit the dealer or phone an locksmith.<br /><br />Keyless entry systems operate by sending radio signals and then scouring for a response signal from the key fob. If the system can recognize the signal, it will trigger to open the doors of the vehicle and also activate the onboard computer. Some systems have another receiver mounted on the car's trunk that opens it automatically when you put your foot under it.<br /><br /><br /><br />Each key fob is assigned a unique digital identification code by the manufacturer. The fob is programmed with a proprietary process called "programming". This requires turning the ignition of the car several times in a specific sequence, and could require pulling levers or buttons or removing the fuse.<br /><br />Once the key fob has been programmed into your car's keyless system, it transmits a digital identification code and a function code to instruct the car to (lock or unlock the trunk). The receiver in the car confirms that the transmitter is the person it claims to be using an authentication and encryption process.

This will require an instrument that records the transmission, and then retransmits it in the event that the system doesn't want it. Most keyless entry systems utilize a rolling code method to stop this. This ensures that each new signal from a transmitter received by a vehicle has a counter that is different from the previous one.<br /><br />Batteries<br /><br />A dead battery is the most common reason for a car remote to not work. It's an easy and cheap fix when you have a spare key fob on your desk to replace the old one with. Luckily, most fobs use regular watch-style batteries that are available at 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 car's manual.<br /><br />Be careful not to harm any antennas or circuits in the case after you have removed the battery. They are likely holding the key fob's programming to your car's specific model and any disruption to them will render it unprogrammable (and probably not work). If you have to move them, do it slowly as some key fobs have fasteners that can easily open and scatter key fob components across your living room.<br /><br />Most key fobs have one hole that can be used with a screwdriver or other pry tool to pop open the case, but 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. Don't apply too much pressure as the case of the key fob is usually composed of plastic and is susceptible to breaking or cracking with too much force.<br /><br />Be sure to ensure that the size and type of the battery to the key fob when you replace it. Some key fobs come with two batteries while others only require one. The wrong battery can make your remote key fob useless.<br /><br />If the problem persists it is possible to try again with your fob's key after installing the new battery. If not it, you'll have to determine whether your key fob is suffering from a more complicated issue that requires a professional diagnosis and repair. If this is the case, you could require it to be reset by a dealer or you may need to buy a replacement key fob completely.<br /><br />Buttons<br /><br />The tiny buttons on your key fob are small, and they're packed with delicate electronic components. It's not a surprise that they'll occasionally fail. The good thing is, when your car's key button stops functioning, there's usually something you can do to fix it yourself.<br /><br />The most common reason a car remote key stops working is because dirt or crud has been trapped between the buttons. To remove this obstruction, carefully remove both the batteries and scrub each button by using a cotton swab, that has been dipped in ruby alcohol. Make sure to dry them completely before installing the batteries.<br /><br />It's also possible that the key fob was harmed somehow, perhaps dropped on concrete or unintentionally scratched by a sharp object. If this is the case using an alternative key fob to check its functionality could reveal that the one you have been damaged and requires to be replaced.<br /><br />Another possibility is that the door lock sensor in your vehicle 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 uncommon for this sensor to break during prolonged use or exposure to weather conditions. Press your key button several times without locking or unlocking your doors. This will reset the sensor.<br /><br />If all other options fail, you can always test the operation of the spare key by attempting to unlock and lock your doors using it. If the spare key doesn't work, you may need to contact a locksmith on call 24 hours a day who offers automobile key repair to get your remote working again.<br /><br />You can change the settings on your computer if your car key button is working but cannot lock or unlock your vehicle. If you have had the same key fob a while, it may require reprogramming every couple of months to to work with your vehicle. It's not optimal, but it's better than buying an entirely new remote.<br /><br />
