Question 1

Are you licensed and insured to work on Cadillac vehicles?

Accepted Answer

Yes. EZ Car Keyz holds a California Bureau of Security and Investigative Services locksmith license (LCO#6792) and carries full insurance. For a 2022 CT4 specifically, that matters because programming a new remote at this generation requires professional diagnostic equipment with active GM security coverage. Not every locksmith keeps those subscriptions current, and without them, a new fob simply cannot be paired to the vehicle. When you call, ask any locksmith directly whether they have current GM coverage for 2022 models. If they hesitate, that tells you what you need to know.

Question 2

How do I know you are not a scam locksmith?

Accepted Answer

Scam locksmiths hit Cadillac owners hard because of the luxury badge. The pattern is consistent: a low number quoted over the phone, then a new and higher number once they are standing next to your car with tools out. Some will invent reasons the job is more complex than expected. Others just count on the owner not wanting to argue.

Real indicators of a legitimate shop: a verifiable business name, reviews you can read, a straight answer on price before anyone drives out, and a technician who can explain the process for your specific vehicle. We have over 100,000 followers across our YouTube and TikTok channels showing exactly how we do this work. You can watch before you call. That transparency is the point.

Question 3

Will the replacement remote work exactly like the original?

Accepted Answer

Yes. A properly programmed replacement remote for your 2022 CT4 will communicate with the vehicle security system the same way the factory fob does. All five buttons function as expected. I test every single one on site before I hand it over, because a partial program is a real thing that happens when the job is rushed or the wrong tooling is used. An owner on a GM forum reported buying a fob online that paired for door locks but never reliably handled other functions. That is what happens when programming is not fully verified. I do not leave until the whole fob checks out.

Question 4

I need a second remote for my CT4. Can you add one without erasing the fob I already have?

Accepted Answer

Yes, and that distinction matters. Adding a key is different from an all-keys-lost job. When you still have a working fob, the process is an add-key procedure, which keeps your existing remote active and enrolls the new one alongside it. All-keys-lost requires a full security reset, which takes longer because the system runs a timed security delay you cannot skip. If you have your original fob in hand when I arrive, the add-key job is faster and simpler. Either way, both procedures require a scan tool. There is no shortcut on a 2022 push-button vehicle.

Question 5

My CT4 is showing a key-not-detected warning but the fob battery is fine. What is going on?

Accepted Answer

A few things can cause this even with a good battery. The antenna that reads the fob inside the cabin can have a wiring issue or a connection that has worked loose. The fob itself can have a failed transponder component even if the buttons still transmit. There are also cases where the vehicle security system loses its pairing record for the fob, which looks exactly like a hardware failure from the driver's seat.

Start by testing whether the warning is consistent or only happens in certain spots in the cabin, since antenna faults sometimes show up as position-dependent. If it is constant and the battery is confirmed good, the next step is reading the vehicle with a scan tool to see whether the system is logging a communication fault or a lost-key fault. Those point in different directions. That diagnostic is something I run on site before assuming a new fob is needed.
