Question 1

Do I need to bring my 2007 Mercedes-Benz CLS somewhere for key replacement?

Accepted Answer

No. EZ Car Keyz is a fully mobile service. We come to wherever your vehicle is, whether that is your driveway, your job, or a parking lot in Imperial Beach. Mercedes dealers require you to either drive in with a working key or tow the vehicle to their service bay. For FBS4 models like the W205 C-Class and W213 E-Class, owners are told "your only option is to take it to the dealership." We handle everything on site so you keep your vehicle the entire time.

Question 2

How does mobile key replacement work?

Accepted Answer

You call us and give us your year, make, model, and VIN. We confirm the right key for your 2007 Mercedes-Benz CLS and give you a price on the phone. We come to your location with everything we need: the key blank, cutting tools, and professional Mercedes programming equipment. We cut the key, program it to your vehicle's EIS/EZS module, sync the remote and keyless go functions, and test everything before we hand you a working key. The whole process happens right next to your car. No tow truck, no waiting room, no second visit.

Question 3

What do I need to have ready when you arrive?

Accepted Answer

Just your vehicle, a valid photo ID, and proof of ownership like your registration. We verify the VIN from your dashboard or door jamb to confirm the key specs. That is the same standard whether you use a locksmith or a dealer. The difference is we handle it curbside instead of sending you to a service counter and then home in an Uber. Mercedes dealers have strict identity verification processes and sometimes require the registered owner to appear in person before they will even order the key.

Question 4

What battery does the 2007 Mercedes-Benz CLS key fob use?

Accepted Answer

The 2007 Mercedes-Benz CLS uses a CR2032 battery. You can find them 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 current Mercedes fob is losing range or acting inconsistent, try a new battery before assuming the key needs to be replaced. On keyless go models, a low battery will trigger a "replace key battery" message on the dash before the key stops working entirely.

Question 5

Can you come to my office or workplace?

Accepted Answer

Absolutely. A big chunk of our calls are to workplaces, office parking lots, and job sites across Imperial Beach. You do not need to take time off to deal with a key issue. One Sprinter owner met a mobile locksmith in a Rite-Aid parking lot and had their key done for $80 instead of dealing with the $1,200 dealer-referred quote. Mercedes owners are often surprised to learn that a mobile locksmith can handle the same EIS/EZS programming at their location that they assumed required a dealer visit.
