Programming remote

[Merrin]

Hi
How do I program a remote to a sentry receiver with dipswitches? It's a 2 button remote. No switches on remote .

You can't.

The buttons are the switches. Should be a jumper to enter programming mode and then one button is off and the other on in sequence.

Can you post a pic of the open remote?
