2020 Chrysler 300 Smart Key Replacement - Fast, Affordable & Professional
She was at a brewery patio in El Cajon on a first date and her purse was gone. Someone grabbed it from the bench. Car keys, wallet, phone. She borrowed the bartender's phone and called the police first, then her roommate, then me.
Her 2020 Chrysler 300 was in the brewery lot with zero keys. The dealer told her roommate they could order a FOBIK but it would take 3 to 5 business days and the car would need to be towed in. They also recommended checking the locks since the stolen FOBIK could still open the doors. Combined estimate was over $700.
I got there that night. All-keys-lost is a different procedure than adding a spare. When you add a key, the car already trusts an existing key and just adds a new one to its list. AKL means I clear the entire key memory and start fresh so the stolen FOBIK can no longer start the engine. I used my IM608 to access the SKIM module, pull the PIN, wipe the old key data, and program two new keys from scratch. Her FOBIK, FCC ID M3M-40821302, was a 5-button key. I decoded the lock, cut the blade, and had both FOBIKs working before her roommate even arrived.
She drove home that night. Total was $283 for two new keys. The dealer estimated $482 plus a tow and a multi-day wait. The stolen FOBIK can still physically enter the door lock but the immobilizer won't let the engine start. She had two fresh keys and the old one was dead to the car.

“I got locked out of my vehicle and also lost my key. Marco came out, made a new key for my Toyota, and got me back on the road. He was professional, friendly, and clearly knows what he is doing.”
“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.”
