If the batteries in your PINsentry have run low, you can replace them. Replacing them is easy - you'll need four LR44 (1.5V) batteries and a small screwdriver.
Use the screwdriver to remove the screw on the back of your PINsentry, and then take off the battery cover. When you replace the batteries, just make sure you put them in the right way up.
Alternatively, you can order a replacement by contacting our Customer Services Team.
