10 pin dip switch gate to smartthings?

I have an Electric gate with 10 pin dip switches for the remote opener and receiver. I want to control through ST so I can open/close from anywhere. Any ideas on how to make it happen?

Post photos of the Remote? Looking to see if it is a 433Mhz or similar basic low frequency transmitter.

The simplest solution may be to use a ThingShield and Arduino with a simple relay to trigger the physical remote (i.e., simulate the button press). It is sometimes the least complicated solution if there is no other way to transmit the correct signal.

If it is a simple signal, the ThingShield solution is still applicable but using a cheap low frequency transmitter module instead of relay.
