How Your Car’s Remote Key System Works

By Jason Bacot

Most newer cars have remote key systems that allow or deny access to the car and ignition. There are several types of remote key systems on the market, made by companies like Philips and Amtel. With this type of car key system you can unlock or lock your car without physical contact with it. These are sometimes called “keyless” systems since you don’t have to put the key into the door lock to open the car, but the term is somewhat of a misnomer since you do actually have functioning keys as part of the system. Keys of this type are commonly called transponder keys.

Most remote key systems work by broadcasting radio waves on a certain frequency – usually 315 MHz in North America, but the systems use encryption techniques to keep car thieves from intercepting signals in order to break into cars. Though operable distances vary by manufacturer, Ford systems work within a 20 meter radius around the car. This can be a great convenience in places like Chicago where it gets extremely cold in winter, because if you’re not sure you locked your car and don’t want to go back out and check, you can usually click the lock button from inside your house to lock your car.

Car locksmiths are specially trained to deal with transponder keys and to make replacement car keys for almost any make and model car. The unique digital identity code for your car keys is usually performed by your car dealer. The car computer is put in programming mode, and procedures vary for programming the car to accept a certain key. Car dealers frequently tell customers to call them if they should lose their keys or otherwise be denied entry to their cars. However, if you are in Chicago and lose your keys, your best bet is to call a Chicago local locksmith, who can perform the same task more quickly and at a far lower cost than what dealers charge for the service.

Your Chicago locksmith, trained in cloning transponder keys, is able to reproduce key fobs that activate a car’s central locking system, allowing you to get into your car without having to have new ones cut. But locksmiths can also tackle tasks like repairing damaged locks. Locks that become chipped or dented sometimes won’t accept your keys, and if it’s your ignition lock that’s damaged, you won’t be able to start your car. It’s very important to have the number on hand for a Chicago area locksmith who can be reached 24/7 if you end up stuck somewhere without your keys, or with keys that won’t operate a damaged lock.

Once the locksmith arrives on the scene, it is usually only a matter of a few minutes for a new transponder key to be coded and functional, and the total cost is usually hundreds less than car dealers charge for the service. Car locksmiths are specially trained in the unique features of car locks, and can use hardware and software kept in their service vans to do the job quickly, and without hassles. Do yourself and your loved ones a favor by programming the number of a trusted locksmith into your phone, so you won’t be stuck having to rely on the Yellow Pages or an internet search to locate a locksmith when you lose your car keys.
