2. Transponder Keys
Introduced in the mid-1990s, these keys include a plastic head containing a small computer chip. When the key is inserted into the ignition, the vehicle's engine control unit (ECU) sends a signal to the chip. If the chip reflects the appropriate digital code, the car starts. If the chip is missing or set improperly, the engine remains debilitated.
3. Integrated Key and Remote
This style integrates the RKE fob and the transponder key into one unit. Often viewed as "flip keys" or "switchblade keys," these supply a compact option but are more expensive to change due to the fact that they need both mechanical cutting and electronic programming.
4. Smart Keys/ Proximity Fobs
The most advanced variation offered today, wise keys utilize distance sensing units to communicate with the lorry.
