Car Key Locksmith in South Oceanside
Third call from the same apartment building on Cassidy Street this year. Different unit, same problem: one key, no spare. This time it was a 2023 Mazda CX-5 with a dead proximity fob after a full day at Buccaneer Park. I pulled the emergency blade from inside the fob housing, unlocked the driver's door manually through the hidden cylinder, then extracted the security PIN and paired a fresh smart key using the Autel IM608. Three tenants in one building, three single-key emergencies, eight months apart.

EVERY KEY TYPE, ONE VAN
Transponder Key Programming
I handle transponder jobs on Hyundai Sonatas and Elantras multiple times a month in South Oceanside. The usual story: someone gets a blade cut at the hardware store, it turns the ignition fine, but the engine won't fire. That blank metal key sends no ID46 chip data, so the immobilizer shuts everything down. A Smart Pro clones the original chip profile, writes it to the new key, and confirms ignition start right at the curb. $145-$185.
Spare & Duplicate Keys
I handle spare key requests on Nissan Altimas more than almost any other sedan down here. Cassidy Street alone has put three on my schedule this quarter. The NSN14 keyway gets decoded with a Lishi pick, the blade gets cut on my Xhorse Dolphin to factory depth specs, and the ID46 transponder gets registered via the diagnostic port. Teenagers heading to El Camino High, new roommates splitting a shared car, all the same request. Transponder spares run $145-$185.
Lockout Service
I handle Subaru Outback and Forester lockouts in South Oceanside weekly. Air wedge in the door frame, coated long-reach rod to the interior unlock switch, back in your seat before the parking meter clicks over. $105-$145.
Ignition Repair & Replacement
I handle more ignition repairs on Ford Rangers in South O than any other truck on my route. Salt air drifting off Buena Vista Lagoon corrodes the HU101 wafer stack until the key barely turns. I pull the cylinder, decode what's left with a Lishi HU101, swap the damaged wafers, and cut a fresh blade that matches the rebuild. If the cylinder walls are scored too deep, a wafer swap won't hold and you need the full housing replaced. I'll tell you which one before any work starts. Ignition jobs run $175-$275.

Kim Wachter"I had lost my keys and Steve came to make me a new one the exact same day! Only like a 30 min wait. I really needed to get to work and Steve helped me out with the entire situation. Great service 10/10."
Gregorio Palma"I lost my car key at the beach. After waiting 4-6 hours for unreliable locksmiths, I called EZ Car Keys. Someone came out within ten minutes and got it done for a fraction of the price. No crazy deposit and no bs."
