If your car turns over but will not start with a new or copied key, the problem is often the chip, not the blade. Austin Snap Keys provides transponder key replacement in Austin, TX, cutting and programming chip keys so your vehicle’s immobilizer recognizes them and lets the engine start, for supported makes and model years.
Most modern cars use a transponder chip hidden in the key head. A key that is only cut can open the door and turn the ignition, but the engine will not run unless the chip is accepted. Our car key replacement service handles the whole job: identifying the chip type, cutting the blade and programming the new key to your car.
Lost Your Only Transponder Key?
Losing the last chip key does not always mean a tow to the dealership. For many supported vehicles, a new transponder key can be cut and programmed even when no working key is left.
An all-keys-lost job usually takes more steps than adding a spare, because the car’s immobilizer has to learn a brand-new key, and on some vehicles the old keys are erased so the lost one can no longer start the car. Tell us whether you still have a working key so we can explain the right process and quote accurately. Proof of ownership is required before any key is made. For help with every key type, see our lost car keys service.
Transponder Key Types We Replace
Transponder chips come in several key styles. If you are not sure which one you have, describe the key or send a photo when you call and we will help identify it.
Standard Chip Keys
A plain metal key with a plastic head that holds the chip. These are common on many older cars and trucks. The blade is cut to your locks, then the chip is programmed or, on some vehicles, a compatible chip is cloned from a working key.
Remote Head Keys With a Chip
These keys combine the blade, the transponder chip and the lock and unlock buttons in one head. The chip must be programmed so the engine starts, and the remote is paired separately so the buttons work. See car key programming for more on how that is done.
Flip Keys
A flip key folds the blade into the remote and also carries a transponder chip. If the hinge is broken but the chip and electronics are fine, a new shell may be enough; if not, a full replacement is cut and programmed. Read key fob replacement vs. repair to compare options.
Laser-Cut (High-Security) Chip Keys
Many vehicles use a thicker, side-milled “laser-cut” blade with a transponder chip in the head. These need the right key-cutting machine as well as chip programming. Many push-to-start smart keys also carry a transponder for backup starting; for those, see our smart key and push-to-start page.
Signs Your Transponder Key Needs Attention
A chip problem can look like a dead battery or a starter fault. These are common signs drivers call about:
- Engine cranks or starts, then dies right away: the immobilizer may not be accepting the key’s chip.
- Security or key light flashes on the dash: often a sign the car does not recognize the key.
- A new copy turns the ignition but will not start: the key was cut but the chip was never programmed.
- One key works and another does not: the chip in the failing key may be damaged, for example after a drop or water exposure.
- Key will not turn at all: usually a worn blade or ignition issue rather than the chip; see why your car key won’t turn or our ignition repair service.

How Transponder Key Replacement Works
The exact steps depend on your vehicle, but most transponder key jobs follow the same basic process.
1. Share Your Vehicle Details
Tell us the year, make and model, and whether the car uses a regular key ignition or push-button start. This tells us which chip and blade are compatible.
2. Tell Us How Many Keys Still Work
Adding a spare while one key still works is usually simpler. With all keys lost, the immobilizer has to be set up for a new key from scratch.
3. Verify Ownership
For security, we confirm that you own the vehicle or are authorized to have keys made before any transponder key is cut or programmed.
4. Cut the Blade and Program the Chip
The blade is cut to your locks and ignition, and the chip is programmed to the vehicle (or cloned from a working key where that is supported) with the right equipment.
5. Test the New Key
Before we finish, the key is tested to start the engine, and any remote buttons are tested too. Ask what the quote includes before work starts. For pricing factors, see our guide to car key replacement cost in Austin.
Spare Transponder Keys and Related Services
The best time to get another chip key is while you still have one that works. A spare is usually quicker and simpler than an all-keys-lost replacement.

Transponder Key Replacement FAQs
What is a transponder key?
A transponder key has a small chip in the head that sends a code to the vehicle’s immobilizer. If the code is not recognized, the engine will not start or will shut off right away, even if the blade turns the ignition.
Can a locksmith replace a transponder key without the original?
For many supported vehicles, yes. A new key can be cut and programmed even when no working key remains. The process depends on the vehicle, and proof of ownership is required.
Why will my copied key unlock the door but not start the car?
The copy was cut but its chip was not programmed to the car. The immobilizer blocks the engine until it recognizes the chip, so the key needs programming.
How much does transponder key replacement cost in Austin?
The price depends on the vehicle, the key type, programming needs and whether all keys are lost. Call Austin Snap Keys at (512) 897-2872 with your year, make and model for a quote.
Is a new transponder key cloned or programmed?
It depends on the vehicle. Some chips can be copied from a working key; others must be programmed to the car’s computer. We will tell you which method your vehicle needs.
Does a transponder key have a battery?
The chip itself does not need a battery. If your key also has lock and unlock buttons, the remote part does use a battery, but a dead remote battery usually will not stop a chip key from starting the car.
Do you offer mobile transponder key replacement in Austin?
Austin Snap Keys offers mobile automotive locksmith service in Austin and nearby areas. Call to confirm availability for your vehicle and location.
How long does transponder key replacement take?
Timing depends on the key type, whether a working key is available and the programming your vehicle needs. Ask for an estimated timeframe when you request your quote.
Should I get a spare transponder key?
Yes, if you only have one. Adding a spare while a key still works is usually simpler than replacing every key after the last one is lost. See our key duplication service.
