Car Key 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.
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.
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.
Text us your year, make, and model for a free quote.
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.
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.
Call or text now and we'll have a price for you in under a minute.
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.
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.
Send us your VIN and we'll confirm the exact price before we head out.
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.
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.
Call or text for a quick quote. We'll match the right key to your vehicle before we roll.
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.
The simplest key we make. No chip, no battery, no programming required. A single edge-cut blade that mechanically operates the door locks and ignition. You'll find these on older tr
Text us and we'll get a spare cut before you need one.
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.
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.
Call or text to get your emergency blade cut while you're thinking about it.
