The cost of replacing a car key depends on many variables, such as the year model, make, and year of your car. It is recommended to check with local locksmiths before visiting the dealer. It is also helpful to have the VIN easily accessible - typically on the dashboard or in the engine bay. Mechanical Keys A mechanical key makes use of a simple switch that senses an amount of force to trigger. The switches are tactile (they reduce their resistance when they receive signals), and some even generate a sound called a "click". The force is measured in grams-force or centinewtons. If a key ceases to function, it's likely that there's an issue with the switch itself or there may be some debris beneath the keycap. Remove the cap of the key to check for any debris. Some keys are printed using the process of dye sublimation which gives the plastic color and makes it a part of the material. This kind of printing is extremely durable and is able to withstand significant wear and tear. Transponder Keys Transponder keys are found in most modern cars to communicate with the vehicle's device. They transmit and receive radio signals. This device, which is also known as an "immobilizer", prevents the vehicle from starting if the frequency has not been properly programmed. Contrary to mechanical keys, which are able to be copied without problem transponder keys require special equipment and programming to duplicate. This makes it harder for novice thieves to hot-wire them, but that does not mean they are invincible. Transponder keys are different from mechanical keys. They are equipped with a chip embedded in the head of the key. The head of the transponder keys is also slightly larger than a normal metal key. In order to work for a transponder key, the chip in the transponder key must send a coded signal to vehicle's ECU (Engine Control Unit). Onc
