Like your other home security devices, it’s important to properly take care of them. Below are a few maintenance tips concerning your key fob. -Make sure your key fob is functioning properly and that the signals reach your home security panel. Look on your panel for warning or other error messages. -Keep track of how many key fobs you have and who you’ve lent the key fobs to. Again, this is why naming each key fob in your home security panel is important, so you can remember who has what key fob. If you don’t keep tabs on your fobs, you run the risk of compromising your overall home security system. -Within your home, key fobs should be kept in a safe spot and not out in the open for intruders to see and then use to disarm your place. -Take note of when you install batteries in the device and set a reminder when they need to be replaced. -Read the owner's manual to better understand your security key fobs and how to best maintain them. If you think your key fob is malfunctioning, call the manufacturer or an alarm technician to come take a look.
