Hey Guys,

I just purchase a 2012 Suburban and it came with 1 key. Do you know how to program a new replacement key without deleting the existing key? I've found some online videos but people are saying that while the new key programming works it deletes the original key. Any help would be appreciated!

 

you need a scan tool to delete keys.
domestic models...put the programmed key in ignition and turn to run, remove key and install the unprogrammed key and turn to run. key off and it should be programmed.
export vehicles...same procedure but you need 2 programmed keys turn to run in sequence before installing the unprogrammed keys.

 

Thanks tech2, appreciate your help!
