1620 Battery you need - https://amzn.to/4cTMJBN

Here is a quick and simple demonstration video on how to replace the dead / weak 1620 batteries in your Lincoln key fob. You can use a flat tip screwdriver to help you but it's not necessary. Pop off the back cover with either your fingernail or the small screwdriver and install the new coin cell 1620 batteries. Make sure they go + side facing down. Clip the back portion back into place and you're all set! No need to reprogram! Hope you found this video helpful!
