## Questions & Answers

**Q: Can you time limit codes for visitors and service personnel**
A: The keypad can have a temporary PIN code set and can be set to work 1 to 99 times before it expires, or it can be deleted. This does not affect the main PIN.

**Q: Did anyone have trouble transferring their garage door code from their opener?**
A: Adding to note from yesterday:  Step 2 is your individual 4-digit security number, which is different from the code copied from the main garage opener unit to the keypad in Step 1.

**Q: Will it work with a m55 series?**
A: It looks like the M-55 is operating with 315Mhz and should work with the keypad.  Google it.    If you buy it---be sure to change batteries before they go dead--that will kill the keypad in my experience.

**Q: I have a 15 year old omega matic, will this work?**
A: It will if the back of your remote has 315Mhz on it
