Key fob

[Scottie]

Just bought a 2015 2500 duramax. How can I unolck the doors using just the key and not set off the horn. I don't like carrying the fob. Thanks, Scott

Lock the door manually. Locking it electrically sets the security system to active. If other doors also need locking, lock with the electric button, unlock the driver door manually, open it, then lock it manually, not with the door button or fob. This should not set the security system to active.

Or, have the security system disabled. I'm not sure on the 2015's, but most prior models required a Tech II. Your delivering dealer (or possibly others) may do it for free. Otherwise, it's 1/4 hour shop time. Check your information center menu and the owner's manual, there may be a means to disable it.
