The new fob will disable your other fobs. So have your them with you when programming the new one they can be reprogrammed at the same time as the new one is programmed. I know it sounds like a pain but it’s really a very easy process. I highly recommend this product programmed it in a few tries and works good. So far, i’ll update. If i have issues the transaction was flawless, the two key fobs arrived together several days before the estimated delivery date programming. The key fobs was simple: it took longer to read the instructions than to program. I would absolutely recommend keyless to go to a friend and would do business with them again delivered. On date, promised programming took about one minute and all buttons work perfectly just like original, including rear, hatch and door couldn’t be happier with the purchase and supply works. Just as good at the oem came with a link to very clear instructions that made programming easy we’ll update review at a future date to comment on the longevity of the unit works. Great easy to self program. For my 2008 lincoln navigator works the rear door and rear hatch separately very prompt delivery. Remotes were easy to program. Now i have two working remotes. Instead of one broken remote, very pleased with our purchase also much more cost effective than going directly to the automotive manufacturer. For replacement remotes, i guess the third time is. The charm have tried two other similar remotes, but none of them would open a lift gate on my o7 navigator.
They would open the glass but not the whole gate. This one does open the gate and works perfectly.
