To program a 2005 Honda Element keyless remote, begin by sitting in the driver's seat and closing all doors. Insert the key into the ignition and turn it to the "On" position (not starting the engine) and back to "Off" five times within 10 seconds. Then, press the "Lock" button on the remote; the doors should lock and unlock to indicate successful programming. Repeat this step for any additional remotes, and finish by turning the ignition back to "On."

Try this: Turn the ignition to RUN (do not start), press the unlock button on the keyless remote, ignition OFF. Repeat 2x. Turn the ignition to RUN, press the unlock button on the keyless remote twice, the power locks should cycle to indicate successful programming. Turn the ignition OFF and test remote.
Replaced the battery in the remote.
Its the same as honda civics. It a series of turning the ignition key off and on while pushing button on the remote. Im sure you can look that up as it's more common
I would try a clock repair shop.
All EX models have key less remote entry. It was a standard feature.
To program a keyless remote control for a 2003 Honda Civic Si, first, sit in the driver's seat and close all doors. Insert the key into the ignition and turn it to the "On" position, then back to "Off" five times within 10 seconds. On the sixth turn, leave it in the "On" position; the doors should lock and unlock to indicate you're in programming mode. Press the "Lock" button on the remote within 5 seconds, and the doors will lock and unlock again, confirming the remote is programmed. Repeat this step for additional remotes, then turn the ignition off to exit programming mode.

Try it manually, with the actual key. If it opens that way, then the remote sending unit is defective.
