![]() There’s many different types of transponder keys – including zero bitted keys and encrypted keys. Usually cars can’t tell the difference between the original key and a cloned copy, so before copying your key, ask the locksmith what kind of key you’re getting. Some car brands (Chevy and Ford) don’t require specialized equipment to program keys – they can be programmed with an OBP (on-board programming) process by the vehicle’s owners – all they need to have is the instructions included in the car manual as well as two existing, pre-programmed, not copied keys. If you want to copy your transponder key, a locksmith can use specialized equipment to clone an existing key for your vehicle. Some companies even use transponders in commercial industrial locks. Since then, almost all vehicles are operated with transponders, including motorcycles. The automobile companies were confronted with data supplied by the insurance industry, claiming that if the manufacturers didn’t act to cut down on the theft rate, the insurers wouldn’t be able to affordably insure new cars. The widespread use of auto-transponders has it’s origins in the early 90s. If the key is cut correctly and turns the cylinder, it still is required to have the correct amount of resistance (Ohms) or else the car will completely shut down, and not even the correct key will be able to start the car – usually the enforced safety lockout lasts 3-4 minutes. For example, GM’s VATS (Vehicle Anti Theft System) keys contain a resistor with 1 of 15 possible preset resistances. Some other more simple chip key types are programmed with an identification number which the car recognizes. If the key has been correctly programmed, it will respond with 9 – allowing the car to start, since it knows the driver is using the proper key. Here’s how it goes down: the key is turned and the car transmits a number, lets say 6, and the car’s internal algorithm (let’s say X plus 5 – 2) processes it. Many recently manufactured password transponder systems work with a rolling encrypted code – an algorithm which involves the car’s transmission of a six digit number, and the transponder’s processing of the code to formulate a unique response. There’s a small microchip inside the plastic head of the key that receives a signal from your car (a ringed antenna around the ignition cylinder.) The computer inside the car must receive the correct response from the transponder key, or it will not allow the vehicle to work. The transponder (formed from transmission/responder) key is part of the car’s anti-theft system. With flat keys, the cuts on the tops and bottoms operate mechanically, simply through the cuts – they match up with the tumblers in the lock, and the key is allowed to turn. Transponder keys are different from automotive remotes that are used to unlock and lock your vehicle some transponder keys are built inside of your keys (in a component called remote key heads) while others are placed separately. Automotive keys can be separated into two groups: transponder keys and non-transponder (flat metal) keys. You might be wondering why your transponder key costs more than a typical manual key.
