Question 1

Are you licensed and insured to work on Lincoln vehicles?

Accepted Answer

Yes. EZ Car Keyz is a California BSIS licensed locksmith company (LCO#6792), fully insured, and NASTF Vehicle Security Professional certified. Smart key work on a 2011 Lincoln MKS involves more than just cutting metal - programming the fob into the vehicle's security system requires the right diagnostic tools, and not every locksmith carries them. Some will show up and tell you Lincoln is dealer-only simply because they don't have the equipment. We operate under a real business name, with verifiable reviews and over eight years of experience. You can confirm the license directly through the California Bureau of Security and Investigative Services.

Question 2

How do I know you're not a scam locksmith?

Accepted Answer

It's a fair question and worth asking. Scam locksmiths are a documented problem in California, and luxury badges tend to make it worse - owners on Lincoln forums have noted that some locksmiths quote higher on arrival just because of the nameplate, then claim the vehicle requires special access or proprietary tools to justify the jump.

The pattern is always the same: low number on the phone, a different number once they're looking at your car.

EZ Car Keyz has over 100,000 followers across YouTube and TikTok where you can watch the actual work being done on Lincoln and Ford platform vehicles. We give a firm price on the phone. We show up in a marked vehicle. The number we quote is the number you pay. That's the whole answer.

Question 3

Will the replacement key work exactly like my original?

Accepted Answer

Yes. The fob gets programmed into your specific vehicle so proximity entry, the start authorization, and the lock and unlock functions all behave the way the original did. Before I hand it to you, I walk every function - both door handles for touch-unlock, the start button, and each fob button - to confirm nothing was missed.

One thing worth knowing: owners on Lincoln forums have reported buying aftermarket fobs online thinking they'd save time, only to find the car's security system flagged the key or that proximity range was off even after programming. The hardware quality matters. Using a proper replacement fob and testing everything on site before leaving is what keeps that from being your problem.

Question 4

My 2011 MKS shows a key warning on the dash but the fob is working. What's going on?

Accepted Answer

This comes up a lot on these cars. Owners report seeing a key-not-detected warning even when the fob still locks and unlocks from a distance, which seems contradictory. Usually it points to the proximity antennas in the door handles or the interior cabin antenna losing consistent communication with the fob - not the fob itself dying.

A low battery will do it intermittently. So will a fob that took a hit or got wet.

Start with the CR2032. If the warning goes away and stays away, that was it. If the warning keeps coming back even after a fresh battery and the fob otherwise works fine, the issue is likely on the vehicle side - antenna wiring or a module not consistently seeing the key - and that's a different conversation than just replacing the fob.

Question 5

I lost both keys to my 2011 MKS. Can you still make a replacement, or does it have to go to the dealer?

Accepted Answer

All-keys-lost on this vehicle is something we handle. It's a longer job than adding a spare when you still have a working key, because the existing key memory has to be cleared and new fobs registered from scratch using diagnostic equipment. The dealer will do the same thing and bill you a luxury rate for the privilege, plus whatever their schedule looks like.

The job gets done on site. You don't need a tow, and you don't need to wait for a dealer appointment. Call with your VIN ready - it speeds things up on our end before we even arrive.
