Another San Antonio homeowner discovered Keep What Works!
We replaced her panel, upgraded her doorbell, and added a spotlight camera while keeping her sensors, locks, thermostat, and garage controls. A fresh start without starting over. Welcome to the kingdom!

Sometimes our customers come up with the best ideas.
The dogs destroyed the last yard sign, so this homeowner mounted ours to a tree instead of staking it in the grass. However you display it, we're honored every time someone stakes the sword.

Think switching security companies means starting over?
Not always.

Many homes already have security systems that work with Alarm.com. If yours qualifies, you may be able to switch to Excalibur without replacing equipment.

Think yours qualifies? Ask us!
