Car Key Replacement Options We Offer

Prices below are typical ranges. Your exact cost depends on year, make, model, and whether all keys have been lost. We'll confirm the price before any work starts.

01

Transponder Key Replacement

Car cranks but won't start? If the security light is flashing on your dash, the transponder chip is the issue. Call us and we'll confirm in under a minute.

EZ Car Keyz technician programming a replacement transponder key for a 2018 Honda Accord in a private driveway in Oxnard, California.

Every transponder key has a tiny RFID chip embedded in the plastic head. When you turn the ignition, an antenna coil in the steering column reads the chip's code and checks it against the engine control unit.

02

Smart Key / Proximity Fob Replacement

Doors won't unlock when you grab the handle? Push-button start not responding? That's a dead or missing proximity fob. We replace them on the spot.

Technician pairing a new proximity fob to a 2019 Nissan Altima in Ventura, California, after the original fob was lost at the beach.

A smart key is a different animal from a transponder. Antennas hidden in the door handles, B-pillars, and trunk lid send out a low-frequency challenge signal; the fob responds with an encrypted rolling code, and if the vehicle verifies it, the doors unlock the moment you touch the handle.

03

Laser-Cut / Sidewinder Key Replacement

Groove down the middle of the blade instead of jagged teeth on the edge? That's a sidewinder, and a regular key shop can't cut it. We can.

Cutting a sidewinder key for a 2017 BMW 3 Series at a customer's garage in Thousand Oaks, California.

Look at your key from the side. If there's a single serpentine groove carved into the center of a thick, flat blade, rather than the jagged teeth along one edge you'd see on a traditional key, you have a sidewinder.

04

Flip Key / Switchblade Key Replacement

Key folds in half like a pocket knife? Blade won't spring out anymore, or the housing cracked from a parking-lot drop? That's our most common call.

Replacing a cracked flip key housing on a 2016 Kia Forte in Simi Valley, California, with a fresh shell and a new blade cut to the original bitting.

Press the button, the blade springs out; fold it back and the whole key fits in your pocket like a Swiss Army knife. Inside the housing you've got three systems in one: a transponder chip that talks to the immobilizer, a remote that locks and unlocks the doors, and a physical blade that turns the ignition.

VW and Audi originally popularized the design, and now it's the go-to for Kia, Hyundai, Chevrolet, Mazda, and Toyota.

05

Standard Metal Key Replacement

Only have one key for an older truck or work rig? A $50 spare now saves a $200 emergency call at midnight.

Cutting a plain mechanical key for a government-issue fleet truck stationed near a base housing area in Camarillo, California. No chip, no electronics, just a code-cut blade calibrated to factory depth on the Xhorse Condor.

The simplest key we make. No chip, no battery, no programming required. A single edge-cut blade that mechanically operates the door cylinders and ignition.

$50-$10015-20 minutes

06

Emergency / Insert Key Replacement

Ever checked if the little blade inside your smart fob is actually there? Most people find out it's missing at the worst possible moment. Let us cut one before that happens.

Cutting a replacement emergency blade for a smart fob on a 2019 Lexus RX at a condo complex in Moorpark, California. The owner's daily salt-air commute chewed through the fob battery and the insert key slot was empty.

Look at the back or bottom edge of your smart fob. There's a small release button or sliding latch. Press it and a thin metal blade pops out. That's your emergency key, and it exists for one reason: getting into your car when the fob's battery is dead or something is jamming the radio signal.

Frequently Asked Questions

What do I need to have ready when you arrive?
Valid photo ID that matches the vehicle registration. If the car isn't registered in your name, bring the title or a notarized authorization from the owner. We verify ownership on every job, no exceptions. It takes about two minutes and protects you as much as it protects us.
Can you come to a parking garage, tow yard, or my workplace?
Anywhere the vehicle is parked. Parking structures, dealership lots, body shops, tow yards, apartment complexes, your driveway at 6 AM before work. If we can physically access the driver's door and OBD-II port, we can make the key. We work in tow yards across Oxnard and Camarillo regularly.
Will my auto insurance or roadside assistance cover the cost?
Most roadside assistance plans (AAA, your insurer's roadside add-on, manufacturer programs) cover lockouts but not key replacement. They'll get someone to open the door, but if you need a new key cut and programmed, that's a separate service. Some comprehensive auto policies reimburse key replacement. Check your policy or call your agent before the appointment and we'll provide whatever receipt or invoice they need.
Can you program a key or fob I already bought online?
Sometimes. Aftermarket blanks from Amazon or eBay work for certain makes and models but not others. Some have the wrong chip frequency, others use housings that don't seat properly in the ignition. If you already have one, tell us the brand and part number before we come out and we'll let you know if it's compatible. If it's not, we carry OEM-spec blanks on every truck so you're not stuck waiting for a second visit.
How many spare keys can you make in one visit?
As many as your vehicle will accept. Most cars allow up to eight transponder keys or proximity fobs in the system at once. We recommend at least two working keys: one on your person and one stored somewhere safe. Programming multiple keys in the same visit is cheaper per key than coming back later because the setup and diagnostic time only happens once.
What if my key snapped off inside the ignition or door lock?
We extract the broken piece first, then cut and program a replacement. Broken extractions are straightforward as long as nobody has already jammed a screwdriver or tweezers in there trying to fish it out. If you break a key, leave the fragment where it is and call us. Trying to force it deeper makes the extraction harder and can damage the lock cylinder.
Do you work on motorcycles, RVs, or commercial fleet vehicles?
Motorcycles with transponder systems, yes. RVs and motorhomes, yes for the chassis ignition key (the home side of locksmithing is a different specialty we don't cover). Commercial fleets, absolutely. We service work trucks, box vans, and equipment vehicles across Ventura County and can set up fleet accounts with volume pricing if you manage more than a handful of vehicles.
How do I know I'm not getting overcharged compared to other locksmiths?
We quote a flat price before we drive out, and that number doesn't change once we're on-site. No service call fees tacked on after the fact, no "oh the part was more expensive than I thought" surprises. The price we text you is the price you pay. If you want to shop around, we encourage it. Most people call back.
