Yes, you can as long as we can program your current system or if your current company does not have “lock out” codes built into your control panel that prevents us from being able to program the system. If we are unable to program, we can provide you with a very affordable upgrade that usually only requires a new control panel and keypad(s)* (*in some cases, we will not be able to use any of your existing equipment depending on age of the equipment or other factors).
