Before changing the batteries or moving any existing security sensors or equipment you will need to put your security system on system test. This can be performed by calling the Tbaytel monitoring station at 807-345-2739 and picking Option 1.

There are several different variations of keyfobs that are compatible with Tbaytel security systems.Each different variation will also have different battery requirements. Most Tbaytel keyfobs requires CR2032 or CR2025 batteries.

  1. Remove the cover by inserting a coin into the slot located on the center bottom and twist
  2. Be careful not to dislodge the button pads, some units have a little screw at the center that needs to be removed to expose the batteries.
  3. Remove the battery(ies)
  4. Leave the unit battery-less for at minimum 30 seconds for the system to detect the drop off.
  5. Install the new battery(ies). Be sure to pay attention to the polarity as to not damage the unit
  6. Reattach the backing
  7. Arm and disarm the system to clear the trouble condition on the keypad

Regardless of the battery you need; you should be able to acquire them from the Tbaytel Retail Store in the Thunder Center; or at most hardware stores.
