Keyless Entry Transmitter Battery: Service and Repair

Battery Removal






1. Remove the set screw to remove the battery from transmitter.
2. Install a battery with its (+) side face-down.

Note: Battery required for replacement - Coin type battery CR2032

3. Insert the claw first, and with care not to displace the 0-ring, assemble the transmitter.



NOTE: Do not let water or dust stick to the inside of the transmitter when its open. Also, do not touch the precision electronic device. If the 0-ring is displaced during the assembly of the transmitter, water or dust penetrates in it, causing trouble.


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.
