open To begin by putting the tool along the outside edge of the case just as you would do when peeling an apple or orange Dont apply too much pressure as the case of the key fob is generally constructed of plastic and it is prone to break or crack with too excessive force Make sure you match the size and style of the battery to the key fob when you replace it Some key fobs come with two batteries while others only need one The wrong battery can make your remote key fob useless After the new battery is installed test your key fob again to see if the battery has fixed your problem If

using a different one Another possibility is that the door sensor for your cars lock isnt working anymore Its a tiny metal component attached to the key fobs door lock button Its not common for it to fail due to weather conditions or long usage To reactivate the sensor just press your key button a few times without locking or unlocking your doors to reset it If nothing else works you can always test the functionality of a spare key by opening and locking your doors using it If the spare key doesnt work you may need to call a locksmith 24 hours a day who can repair your car keys to get your remote working again If your car key button is working but its still not locking or unlocking the vehicle try to reprogram your computer system Be aware that if youve owned the same key fob for a
