Smart car keys are truly “keyless” in the sense that they rely completely on electronics to operate. A smart key fob has no metal shaft to actually insert in the ignition, and the car is started by pushing a button rather than inserting a key. Inside the fob of your smart key there is a transponder chip which communicates with your car’s security system and disarms the immobilizer so the car can start. The fob typically also has remote control function buttons that operate the door locks, release the trunk, open and close tailgates, and loudly blast your horn if you are being threatened.
Today’s cars are built with electronic anti-theft devices that include immobilizers. These add an additional layer of protection against theft, because the immobilizer won’t allow the car to start if the computer does not detect the presence of the correct ignition key. This is an especially important deterrent to hot-wiring, because the immobilizer prevents the car from operating without the key. The transponder’s job is to emit a radio signal that tells the car’s computer to it is okay to allow the car to start.
Like all electronic devices, at some point, your smart key will stop working. If it happens when the key is still new, it could be a defect. These keys also contain batteries that power the controls, so periodically, you will need to replace the battery. Sometimes, the key mysteriously loses its programming and can no longer “tell” the car that it is the correct key. If that happens, you may be able to reprogram your existing key, or you may need to purchase a new one and have it programmed to your car.
We don’t recommend buying replacement car keys online. The quality varies wildly, and you really have no idea what you are getting. Some of them are poor-quality aftermarket keys. Others are made with refurbished chips from other car keys. In some cases, these refurbished chips were only good for one programming. Once the chip is put into a new key, the chips may be basically “locked,” so they cannot be reprogrammed to work in another car.
Your best option is to call Lock N More. We have a wide range of keys for virtually any make, year and model car, and we can replace your smart key with an OEM key that we will program for you.
