## Questions & Answers

**Q: ADT wouldn't tell me how to sync with my system; does anyone know where I can find instructions on how to do this?**
A: Go to dsc website. You will need to have the installers code. He should have either given you the 4 digit code or changed it to your choice. On the keypad hit *8 code then 804 then follow the fob's instructions

**Q: Can anyone suggest how to prevent buttons from being pushed while the fob is in my pocket? I keep tripping the panic alarm by just sitting or leaning.**
A: Happens to me all the time with my GMC truck remote.  I just put a piece of clear scotch tape over the button and it stops accidental pushes.  You'll still be able to push the button if you ever need to.

**Q: How long do the fobs last**
A: Actually they last a long time but what does break is the plastic loop that holds the fob onto your keychain. The two that I've replaced have been because of a broken loop.

**Q: How to replace the battery?**
A: I'm sure you can but I've never had to replace one yet.
