Car Key Locksmith in Rancho Penasquitos
Back from the trail, sun going down, and the 4Runner is still locked at the Los Penasquitos Canyon Preserve lot. Fob lost somewhere on the seven-mile creek loop, phone battery dying, parking area emptying out. I got the call at 6:40 on a Saturday. By the time I pulled into the dirt lot off Black Mountain Road, the owner had already turned every pocket inside out. TOY48 laser keyway, H-chip transponder, push-to-start system. I decoded the lock cylinder, cut a new proximity key on the Xhorse Condor, and synced it to the immobilizer using the Smart Pro running off my battery power station. Engine fired on the first press. Thirty-five minutes from arrival to departure, no external power source needed.

CUT, PROGRAM, EXTRACT
Transponder Key Programming
At the Black Mountain Open Space Park lot, no tow truck is coming fast. I bring the Xhorse Condor and a full set of Toyota transponder blanks running on battery power. Tacoma owner had a hardware store copy that cranked the starter for two seconds and died. No chip in the blank. The immobilizer doesn't care about blade shape. It cares about the encrypted signal, and bare metal sends nothing. Cut a proper TOY43R transponder key and registered it to the ECU via the diagnostic port. $145-$185.
Push-to-Start / Smart Key
At the west-end trailhead of Los Penasquitos Canyon Preserve, no tow truck is coming fast. I bring the Smart Pro, a battery power station, and OEM-spec proximity blanks. 4Runner owner lost their only smart key somewhere along the creek crossing. H-chip system, TOY48 laser cut, push-to-start. Here's what most people don't expect: the security wait cycle runs about ten minutes, and there's no shortcut around it. I decoded the lock, cut the emergency blade, and wrote the new fob to the immobilizer at the vehicle's data port. Forty-five minutes total, mandatory timer included. $245-$325.
Lockout Service
At Canyonside Community Park, no tow truck is coming fast. I bring an air wedge and long-reach tool. Outback locked with the hatch down and keys visible on the passenger seat. Popped the lock in under eight minutes. $105-$145.
Car Key Replacement
At Penasquitos Creek Park, no tow truck is coming fast. I bring a Lishi Y170 pick-decoder and a portable key machine on battery power. Wrangler owner with zero working keys after the only one snapped off in the ignition. Picked and decoded the lock in one pass, cut a new Sentry Key blank, and paired it through the Sentry Key immobilizer module. The broken piece came out of the cylinder clean. $175-$225.

What San Diego Customers Say
"I needed a programmed key and fob for my Honda CRV. I was mistaken about the year of my car, but Marco helped me and got me going quickly. My new key and fob work perfectly. He was nothing but professional and courteous."
Ieshyah Lopez"Simply amazing. They honored their phone quote even though the job took much longer due to problems with my ignition cylinder. They disassembled, repaired, made two new keys and programmed key fobs - all for the original quote."
Michael Schlemmer"This is the second time I've called EZ Car Keyz to rescue me. Tim got the job done again. Great communicator and fantastic service. Their prices are very fair and he comes to you. You can't beat this service."
