Nitro Pro Help: How to Change the Battery in Your Nitro Pro Tag

Written by

Your Nitro Pro CAN-IMMO immobiliser tag runs on a small coin cell battery. Like any key fob battery it will eventually run down, but changing it takes a couple of minutes and you can do it yourself at home. Watch the short video below, then use the checklist to make sure you get it right first time.

Which battery does the Nitro Pro tag use?

The Nitro Pro tag takes a CR2032 3V lithium coin cell — one of the most common button batteries, available from supermarkets, chemists and online. We recommend a good-quality branded battery for the best life.

Signs your tag battery is running low

  • The tag isn’t being recognised as reliably as it used to
  • You have to hold the tag closer to the car or wait longer before you can drive away
  • It has been a long time since the battery was last changed

If you use a PIN code as well as, or instead of, the tag, keep it to hand — it means you can still drive the car if the tag battery dies unexpectedly.

Changing the battery: quick checklist

  1. Have a new CR2032 battery and a small Phillips screwdriver ready before you start.
  2. Undo the two small Phillips screws on the tag and put them somewhere safe — they’re tiny and easy to lose.
  3. Slide the cover off the tag.
  4. Gently pop the case apart to reach the battery — take your time so you don’t damage the clips or the circuit board.
  5. Note which way up the old battery sits, then remove it.
  6. Fit the new CR2032 the same way round, with the correct side facing up.
  7. Pop the case back together, slide the cover back on and refit the two screws — snug, but don’t overtighten them.
  8. Test the tag at the car before you set off.
