Question 1

Are you licensed and insured to work on BMW vehicles in California?

Accepted Answer

Yes. EZ Car Keyz is licensed through the California Bureau of Security and Investigative Services, which is the state body that regulates automotive locksmiths. We carry full liability insurance.

BMW smart key work involves re-pairing fobs to the vehicle's security system through the diagnostic port. You want someone who knows these systems specifically, not a general locksmith who dabbles. We work on BMWs regularly and use the right equipment for the job, which matters a lot on these vehicles. A tech using the wrong tool or the wrong procedure can corrupt the key registry, and that turns a pairing job into a much bigger problem.

Ask any locksmith you call for their BSIS license number before they come out. That is not optional in California - it is the law.

Question 2

How do I know I am not getting scammed by a locksmith?

Accepted Answer

Three things to check before anyone rolls.

Ask for the BSIS license number on the phone. Ask for a firm price for your specific vehicle. Ask if the price is all-in or if there are add-ons when they arrive. Scam operations quote one number on the phone and find creative reasons to double it in your driveway.

Red flags specific to BMW work: a vague quote like "depends what we find," a fob that requires multiple button presses to respond after the job, or a tech who cannot tell you what tool they are using to access the vehicle's key registry. These are signs the job was not done correctly.

We show up in a marked vehicle, give you the price before we touch the car, and that price does not move.

Question 3

Will the replacement key work exactly like the original on my 2014 BMW 4 Series?

Accepted Answer

Yes. A properly done replacement means the new fob is fully enrolled in the vehicle's security system, the start button recognizes it, and the remote functions all operate the way they should. We test every button and every function before we leave.

The reason this question comes up on BMW forums is that there is a real failure mode when the job is done wrong. If the fob gets partially registered or the enrollment process is interrupted, you can end up with a key that starts the car but loses remote functions, or a key that unlocks doors but is not recognized at the start button. We have seen cars come to us after a botched job elsewhere. The right tools and the right procedure matter on these.

We do not leave a job until the replacement behaves like the original. If something is off, we work it out on site.

Question 4

My 2014 BMW 4 Series shows a key warning on the dash but the car still starts fine. What does that mean?

Accepted Answer

That is usually the car telling you the fob battery is getting low, not that the key is failing. The vehicle's security system can still authorize a start when the battery has enough juice left, but it flags the low voltage before you lose full functionality.

Swap the CR2032 first. Make sure you seat it correctly with the positive side oriented the way the tray shows - a slightly misaligned battery will read as a low or missing battery even when it is brand new.

If the warning clears after the swap, you are done. If it comes back or if the fob behavior is still inconsistent after a fresh battery, then it is worth having the fob and the key registry looked at. Sometimes a fob that has been warning for a while will need a re-pairing after the battery fully died at some point.

Question 5

I lost both keys to my 2014 BMW 4 Series. Can you still make a replacement?

Accepted Answer

Yes, all-keys-lost on a 2014 BMW 4 Series is a job we handle. It is more involved than adding a key to a vehicle that already has a working fob, and it takes longer - usually closer to the 60-minute end of the range rather than 30.

The process requires connecting through the diagnostic port, clearing the existing key registry so the lost fobs cannot be used to start the car, and enrolling the new key fresh. There is a timed sequence built into the process that you cannot rush. Ownership verification is part of how I work - title or registration before I touch anything on an all-keys-lost job.

Worth noting: if you have been driving on one key and it goes missing, do not wait. Getting a second key made while you still have the first one is a much simpler job and costs less than starting from zero.
