Q: How do I know you are not a scam locksmith?

Ask for a license number, a written estimate for your specific BMW model, and the company name before they roll. Scam locksmiths quote low on the phone and inflate the price in your driveway. One owner was quoted 499 by phone, then pressured into paying 899 on site for a key that barely worked. The blade was not even cut properly and the fob required clicking the button ten times to get a response. We give you a firm price on the phone for your specific BMW model, show up in a branded vehicle, and the price does not change.

Q: Will the replacement key work exactly like the original?

Yes. We program both the transponder for engine start authorization and the remote functions for lock, unlock, trunk, and comfort access if your 2016 BMW 4 Series is equipped with it. We test everything before we leave. BMW forums are full of warnings about locksmiths who brick CAS and FEM modules using the wrong tools. One experienced locksmith said too many techs with only basic equipment are damaging BMW modules and the bricked cars end up towed to his shop. We use BMW-specific tools and follow proper procedures.

Q: What battery does the 2016 BMW 4 Series key fob use?

The 2016 BMW 4 Series uses a CR2032 battery. You can pick one up at most auto parts stores or pharmacies for a few dollars. When we make a replacement key, we always install a fresh battery so you are starting with a full charge. If your BMW fob is losing comfort access range or the remote is intermittent, a new battery is the first thing to try before assuming the key needs to be replaced.

Q: What happens if something goes wrong after you leave?

We warranty our work. If the key we made has any issue under normal use, we come back and fix it or replace it. BMW owners who buy cheap keys online or use unqualified locksmiths risk corrupting the CAS or FEM module, which can cost four figures to replace at the dealer. One owner paid 600 for a dealer key and immediately complained about cheap plastic construction and visible seam lines. With us, if we made the key and something goes wrong, we take care of it.

2016 BMW 4 Series Smart key Replacement - Fast, Affordable & Professional

Older BMWs with the HU58 blade key are among the faster European key jobs I do. The lock decodes clean, the blade cuts on my machine, and the EWS transponder programming finishes in minutes. A spare key with a working original can be done in 25 minutes flat on most pre-2006 BMW models.

A driver at a rest stop off the freeway near College Area had his key catch in the ignition of his 2016 BMW 4 Series. The blade was visibly worn and the wafers were grabbing. He could feel it about to snap and didn't want to force it. I could hear the worry in his voice when he called.

I used my HU58 Lishi to decode the lock from the door side where the wafers were still clean, then cut a fresh key and programmed the transponder. His CAS3 key, FCC ID NBGIDGNG1, just needed a new blade with a matched chip. The programming took one OBD sequence and the car started on the first turn.

He was back on the freeway in under an hour from when he called, and the total was 346. Dealer would have charged 628 plus a tow and a multi-day wait. A worn blade at a rest stop feels like the trip is over. For older BMWs with the HU58 or HU92 keyway, it's actually one of the quickest jobs I run.

“Tim was GREAT. I honestly swear he must have had my keys made before he even showed up. The entire process was insanely fast, from the initial phone call to having the keys in my hand. No one will beat the pricing, efficiency, or outstanding service.”

Yes. EZ Car Keyz is licensed by the California Bureau of Security and Investigative Services, which is the state agency that regulates locksmiths. We carry full liability insurance and are NASTF Vehicle Security Professional certified, which means we have passed the background checks and credentialing required to access security data for BMW and other manufacturers. BMW key work involves accessing encrypted CAS, FEM, and BDC modules, and you want someone with the proper credentials and insurance handling that on your vehicle.
