2016 BMW Z4 Replacement - Fast, Affordable & Professional
A guy in the Fremont North neighborhood in Oxnard called me about his 2016 Z4 sDrive28i. He had one key left and the dealer had quoted him a number that made him put it off for months. Then the plastic housing on that last key started cracking near the blade release button, and he figured waiting any longer was just gambling.
I met him in his parking garage on a Tuesday afternoon. The Z4 was tucked in a tight spot, nose-first, so I worked from the driver door. I used my HU92 Lishi to decode the door cylinder, reading each wafer position to get the blade cut. Ten cuts on the HU92 profile, and you have to be precise because the tolerances on these are tight. One wafer misread and the blade will bind at the steering lock.
Cut the blade on my mobile machine, then plugged into the OBD port to access the CAS3+ module. Programmed the new transponder into one of the open key slots, synced the remote functions, and tested the start cycle. Blade turned the backup lock, remote locked and unlocked, engine fired clean.
He held both keys side by side for a second like he was just relieved to have a backup. No tow, no dealer appointment, no waiting on a parts order. Just one visit in his own garage.

“This is the only locksmith anyone should ever call. I am still shocked at how fast he arrived and the price was hundreds less than other quotes I received. Honest, professional, and extremely efficient.”
“Locked out on a weekend night and everyone else wanted $300+. EZ Car Keyz sent Roman late at night for much less. He worked for over an hour and did not give up until the door opened. They even made a new key on the spot.”
“I had two Subaru key fobs made and Marco provided excellent service. He stayed persistent through multiple part orders to make sure everything was correct. Very thorough, punctual, and great communication throughout.”
