Car Key Locksmith in Simi Hills
That $3 key from the hardware store opened the door fine. Then the security light started flashing. Guy in Simi Hills called me about his F-150 doing exactly this. Blade turned, engine cranked, theft light lit up, truck died. Hardware store blanks are just brass. No transponder chip, no signal, nothing for the PATS module to read. The truck's computer saw the cylinder rotate but got zero encrypted response, so it killed fuel delivery. I programmed a fresh 80-bit PATS chip with the Smart Pro at his curb off Madera Rd, and the truck started on the first turn.

TECHNICAL SERVICES ON-SITE
Car Key Replacement
The reason your Honda Accord won't recognize that aftermarket key is the immobilizer chip doesn't match. The 2008-2012 Accord uses an ID46 chip. 2013 and newer switched to a G-chip, completely different protocol. I decode the lock with a Lishi HON66, cut a fresh blade on the Condor, and register the correct chip at the diagnostic port. An Accord owner near Royal Ave brought me three dead keys he'd bought online. All wrong chip type. Fifteen minutes with the right blank and he was driving. Transponder key runs $145-$185.
Lockout Service
The reason your Camry door won't open is the interior linkage is locked and no signal is reaching it. Air wedge, long-reach tool, careful pressure on the frame gap to avoid the trim. Five minutes at Simi Valley Town Center. Lockout runs $95-$125.
Transponder Key Programming
The reason your F-150 cranks but immediately dies is the PATS transceiver ring isn't picking up a chip signal. That hardware store key has no transponder glass in the head. I program a proper 80-bit chip using the Smart Pro and sync it to the PATS module. The 80-bit generation has a ten-minute security timer in the learn cycle, so this one takes patience. Transponder key runs $145-$185.
Ignition Repair and Replacement
The reason your Chevy Silverado ignition won't turn is worn wafers inside the lock cylinder. Years of use grinds the brass down. After 150,000 miles they're so rounded the sidebar can't engage. I pull the cylinder, rebuild it with fresh wafers matched to your key code, and test before buttoning up. If the housing is cracked from someone forcing it, a rebuild won't hold and you need the full replacement. Ignition repair runs $150-$250.

What Simi Valley Customers Say
"Even though the name says "EZ Car Keyz", Tim was able to get into my locked house. Others said they'd have to drill the lock out. Tim used his special tool to read the key pattern and made a new key right on the spot within minutes. Then made me a couple extra keys! Super fair pricing."
Dan Hittle"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"The dealership quoted over $500 for a new key fob. EZ Keyz quoted less than half. They got to my home 15 minutes after I called and had it completed in less than 15 minutes. Very friendly, great service."
