🔧 PRO TIP
The 2018+ WK2 adds the security gateway module that blocks key programming until you bypass it. SGW sits behind the passenger lower dash, takes about 10 minutes to access with a 12+8 cable before any programming starts.

2021 Jeep Grand Cherokee Smart Key Replacement - Fast, Affordable & Professional

BSIS license number LCO#6792 is publicly searchable on the California Bureau of Security and Investigative Services website. You can look it up right now. That license means I passed DOJ and FBI background checks, maintain active liability insurance, and run a registered locksmith business.

A veterinarian at the animal hospital in Rancho Bernardo told me she checks every service provider before giving them access to her vehicle. She had a 2021 Jeep Grand Cherokee and needed a spare smart key. She'd already verified my BSIS license, read through my Google reviews, and scrolled my YouTube channel before she ever picked up the phone. I told her I appreciated the diligence.

I used my ACDP to pull her wireless control module data as a safety backup before programming. NASTF certification gives me authorized access to Jeep factory key data, which means correct PIN codes and factory sequences. Her fob, FCC ID M3N-40821302, was a 5-button proximity key programmed through the correct data path.

Her spare cost $259. Dealer quoted $444. Good. Look up the license. Read the reviews. Watch the videos. I want informed customers.

“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.”

“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.”

Jeep Grand Cherokee Mobile Service FAQ

Real costs, no dealer surprises

Are you licensed and insured to work on Jeep vehicles?
Yes. EZ Car Keyz is a California BSIS licensed locksmith company (LCO#6792), fully insured, and NASTF Vehicle Security Professional certified. Jeep key work on newer models requires tools capable of working through the Stellantis secured gateway module. Not every automotive locksmith invests in that equipment, which is why some refuse Jeep jobs or tell you only the dealer can do it. We have the tools, the training, and over eight years of experience to handle Jeep key programming on site.
