“My ignition would not turn in La Jolla and I thought I needed a tow. EZ Car Keyz repaired the ignition on the spot and also made a spare key for safety. The technician worked carefully and confidently.”

“Niv showed up, did his thing, and just like that I had two new keys for a fraction of what the dealership quoted. I have zero reservations recommending him to anyone who needs car keys replaced.”

“We had one broken key for our Honda Civic and one working key for our Lexus. Tim came out and cut three remote car keys at a great price. All keys worked perfectly. Professional, courteous, and highly recommended.”

Mercedes-Benz E-Class Mobile Service FAQ

Real costs, no dealer surprises

How long does a 2003 Mercedes-Benz E-Class key replacement take?
Most Mercedes key replacements take 30 to 60 minutes once we are at your vehicle, depending on the model and whether it is an add-a-key or all-keys-lost situation. A straightforward add-a-key where we program to an open slot in the EIS is on the faster end. An all-keys-lost job that requires EIS extraction and bench work takes longer. Either way, you are looking at well under two hours from arrival to a working, tested key in your hand. Compare that to Mercedes owners who report waiting one to six weeks for a dealer-ordered key.
