Got a chip key? We program transponder, remote keys.
Understanding transponder keys.
A transponder chip disarms a vehicle immobilizer when the car key is used to start hout any buttons, the key must be cut correctly to turn the locks and also programmed correctly to disarm the immobilizer. Car keys with chips can be programmed using special programmers. Lock Stop can program just about any chip key.
Samples of different chips inside your car key.
EEPROM (electrically erasable programmable read-only memory) is user-modifiable read-only memory (ROM) that can be erased and reprogrammed (written to) repeatedly through the application of higher than normal electrical voltage. Unlike EPROM chips, EEPROMs do not need to be removed from the computer to be modified. However, an EEPROM chip has to be erased and reprogrammed in its entirety, not selectively. It also has a limited life - that is, the number of times it can be reprogrammed is limited to tens or hundreds of thousands of times. In an EEPROM that is frequently reprogrammed while the computer is in use, the life of the EEPROM can be an important design consideration.
A special form of EEPROM is flash memory, which uses normal PC voltages for erasure and reprogramming.
