2019 Lincoln MKZ Smart Key Replacement - Fast, Affordable & Professional
When a 2019 Lincoln MKZ key is done wrong, it doesn't "kind of work." It fails. The remote might lock and unlock perfectly while the theft light flashes fast during cranking and the engine never starts. Or push-to-start works a few times, then the BCM runs a deeper security check and rejects the fob entirely.
A warehouse manager at the distribution center in Fallbrook had a key from another locksmith for his MKZ that stopped working after about eight days. It would start in the morning, then by evening the theft light would flash and push-to-start would say "No key detected." He thought the car had an electrical problem.
The other locksmith had used the wrong transponder chip generation. His MKZ needs a 4D63 80-bit chip, and using a 40-bit chip can pass initial programming but fail after deeper security verification over multiple start cycles. I used my VVDI2 to read what chip was in his bad key, confirmed it was wrong, and programmed a new key with the correct 80-bit chip. His fob, FCC ID M3N-A2C940780, also had a weak CR2450 battery making detection worse.
The replacement has been working for months and cost him $291. Dealer would have charged $542. The difference is the chip inside.

“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”
“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”
“I called over 40 locksmiths trying to get a key made for my Audi A6 and nobody could do it. Tim made it easy, fast, and affordable. He showed up with a smile and got the job done without any stress. Absolute wizard with keys.”
