🔧 PRO TIP
The 2010 CTS smart key (FCC ID M3N5WY7777A, part 25943676) runs a Hitag2 ID46 chip through the Body Control Module. The emergency blade is HU100 profile. If you get "No Remote Detected" on the DIC, swap the CR2032 first, but also try the console slot. That molded pocket below the armrest lid bypasses the proximity antennas entirely and lets you start the car with a dead fob battery. If the slot trick fails too, the problem is the fob's chip or the BCM, not the battery.

2010 Cadillac CTS Smart Key Replacement - Fast, Affordable & Professional

A guy visiting his daughter for Thanksgiving near the Newbury Park area called me about his 2010 Cadillac CTS. He had one working smart key and wanted a spare, but not a drawer spare. He wanted to carry it daily and trust it like the original.

Fair question. And it deserves an honest answer instead of a sales pitch.

I showed him both options on the hood of his car. OEM fob, Cadillac crest on the back, GM part number 25943676. Then the aftermarket blank I carry, same five-button layout, same M3N5WY7777A circuit board, same ID46 transponder spec for his BCM. The HU100 blade blank is the same profile either way. I cut it to his door on site.

Programming was the standard GM proximity add-key procedure: existing fob in the console slot, cycle the Start/Stop, then register the new one within the timed window. BCM accepted it first pass. Walked all four doors checking passive entry range, tested the remote start button from across his daughter's driveway, and ran the push-button start three times cold.

The only visible difference between his new key and the original is the missing crest logo on the housing. He pocketed it and said he'd probably lose track of which was which by Monday.

He paid a fraction of what the dealer quoted him. And he never left the driveway.

“We had one broken key for our Honda Civic and one working key for our Lexus. Tim came out and cut three remote car keys at a great price. All keys worked perfectly. Professional, courteous, and highly recommended.”

Cadillac CTS Mobile Service FAQ

Real costs, no dealer surprises

I lost every key for my 2010 Cadillac CTS. Can you still make one?
Yep. All-keys-lost on the second-gen CTS is a standard job for us. We connect to the OBD-II port, run the GM theft deterrent relearn through the BCM (module number 20939745 on most 2010 CTS builds), register the new ID46 smart key, and cut the HU100 emergency blade on site. The old missing fobs get wiped from memory so they can't start or unlock anything. The whole job runs about 30 to 45 minutes at your location in Thousand Oaks near the Newbury Park area. No tow truck, no dealer wait. Way less than what the Cadillac store would charge after you add towing and their shop time.
Can you delete lost or stolen smart keys so they no longer work on my CTS?
Does my 2010 CTS smart key have a hidden emergency blade inside it?
My CTS shows "Service Theft Deterrent System" on the dash. Is my smart key bad?
Will my 2010 CTS smart key work after I replace the battery myself?
