Cannot open boot from remote

[jas0nt]

I recently bought a Honda Accord Euro (2004) second hand. Everything is flawless but I can't seem to open the boot from either of the two remotes I've been given. The other functions on the remotes (lock and unlock) works.

I read through the manual and discovered a switch inside the boot. Regardless of whether it's set to "off" or "on", the remote still can't open it.

The boot lever to the right hand side of the driver's seat works without any problems.

Any suggestions?

Thanks.
