2003 BMW M5 Remote Head Key Replacement - Fast, Affordable & Professional
He was at the craft brewery near the Encanto Border side of Lemon Grove when he noticed his jacket was gone from the back of his chair. Keys, wallet, phone. He borrowed the bartender's phone, called the police, then his wife, then me.
His 2003 BMW M5 was sitting in the lot with zero keys. The dealer told his wife the car would need to be towed in, it would take four to five business days, and they were recommending a full immobilizer service since the stolen fob could still open the doors. The estimate was not small.
I was there within the hour. All-keys-lost on an E39 means wiping the existing key data so the stolen fob becomes electronically useless, then enrolling fresh keys from scratch. I accessed the immobilizer through the diagnostic port, cleared the old key slots, and registered two new remote head keys. The blade on this car is a specific profile, so I decoded the lock cylinder and cut both blades on site.
His wife pulled into the lot just as I was finishing the second key. He drove the M5 home that night. Two working fobs, the stolen one permanently locked out. The dealer's route would have cost him the car for almost a week on top of a tow fee. He saved a good chunk and slept in his own house.
The part that stuck with me: he kept saying the dealer acted like there was no other option. There was.

“I needed a car key replacement in Hillcrest and EZ Car Keyz helped me immediately. The technician programmed a new smart key right next to my car and tested every function before leaving. Fast, friendly, and very professional.”
“The dealership quoted me $600 for a new Honda key. EZ Car Keyz did it for $225, same day, cut and programmed at my house. Works perfectly. Everyone should know this is an option.”
“A+ service at an even better price. Tim was a lifesaver. I lost my original and only key for my Audi and he was willing to come to my location at 8pm the same day. He worked fast, communicated clearly, and made sure everything worked before leaving.”
