Honda Remote Programming by Cycling the Ignition

You can program Honda keyless remotes yourself by cycling the ignition. This erases all current remotes, so reprogram every remote you use (up to 3). Do each step within 5 seconds of the last, or the car drops out of programming mode.

1. 1Turn the ignition to ON (II) and press LOCK or UNLOCK on any remote (an unprogrammed one is fine).
2. 2Turn the ignition back to ACCESSORY (I) or LOCK (0).
3. 3Repeat that pair — ON then press, then back to ACC/LOCK — three more times (four times total). On the last one, the door locks cycle to confirm programming mode.
4. 4With the locks cycling confirmed, press LOCK or UNLOCK on each remote you want to program. The locks cycle after each to confirm it was accepted.
5. 5Turn the ignition to LOCK (0) to exit programming mode, then test the remotes.
