Keyless Entry Transmitter: Service and Repair

Reprogramming Code procedure


Note: Since the transmitter is memorized by each individual code, it is necessary to register a code on EEPROM in the control unit it the transmitter or control unit is replaced, or cause of the trouble is presumed to be due to faulty registration of the code. Since two different codes at the most can be memorized in the memory space of EEPROM, the old code will become unable to be used if the following registration operation is repeated twice. Meanwhile, register a code after confirming that an ordinary door lock function can be worked through key operation.






1. Set the code registration switch of the control unit to SET I (registration mode side).






2. Push the LOCK or UNLOCK switch of transmitter.






3. Set the code registration switch of the control unit to FIX (operation mode) side.
4. Confirm that the keyless entry system operates normally. The registration is completed, if operates normally. If not, repeat (1) - (3).

NOTE: Confirm that after a code has been registered the registration switch is surely set to FIX. In case there are two transmitters, register a code on SET II side in the same manner as SET I.
