This TSB applies to 2013 Honda Accords and Crosstour models. Either one or both keyless remotes do not lock or unlock the doors, or the engine will not start unless the remote is placed very close to the engine start/stop button.
The probable cause is faulty keyless access control unit software. The corrective action involves replacing the keyless access control unit.
NOTE: Before replacing the keyless access control unit, you must have all of the customer’s keyless remotes. If not, all missing remotes will have to be registered during a subsequent repair.

Try to unlock the vehicle doors with the keyless remote (make sure that the battery in the remote is good by checking the LED operation), and try to start the engine with the keyless remote in your pocket. If the engine will not start, place the keyless remote close to the engine start/stop button and try to start again.

- If you cannot lock/unlock the doors or start the engine unless the keyless remote is very close to the start/stop button, go to the repair procedure.
