The key code for many Honda Elite scooters manufactured between 1984 and 2007 can be found stamped on the ignition lock. The Honda Elite scooter models include the CH80, CH125, CH150 and CH250. The key code includes 3 characters and is part of a 6 character string stamped on the lock. The key code is the last 3 characters in this string and begins with a letter followed by 2 numbers. See photo's below.

Most Honda motorcycle and scooter key codes manufactured after 1983 follow this same format. Honda motorcycle key codes before 1983 are also 3 characters, but are all numbers.

The key code is stamped near the round metal rod that pops out of the ignition lock to lock the forks or steering. You have to remove the lock to see the key code.
