If you have one working car key, now is the best time to get a copy. With a working key in hand, we can usually cut and program a spare at your home or office in one visit. It typically costs less and takes less time than replacing keys after they are all lost. Public Locksmith is a licensed, mobile locksmith (NC License #2721) serving Charlotte, Ballantyne, Matthews, Pineville, Waxhaw, Weddington, Fort Mill, Indian Land, Tega Cay and Rock Hill.
Why a Spare Is Cheapest Right Now
A working key gives us a lot to work with:
- The cut is easy to match. We can read the existing key or cut by code from the VIN. We don’t have to decode the door lock.
- The car is already unlocked and running. We don’t need to open the car first or work around a car that won’t start.
- Programming is simpler. Many vehicles let us add a new key while an existing key is present. Some can only be cloned from a working chip.
When every key is gone, the job becomes an all-keys-lost job. That can mean opening the car, decoding the lock and reading security data before a key can be made. Each step adds time. That is why one spare now often saves trouble later.
Signs You Should Get a Copy Made
- You have only one key or fob for the car.
- Your only key has a cracked case, worn blade or loose buttons.
- You bought a used car that came with a single key.
- A new driver in the house needs their own key.
- You share a car and keep handing one key back and forth.
Chip Cloning vs. Onboard Programming
Most cars built in the last few decades have a transponder chip in the key. The car’s immobilizer checks that chip before it will start. Cutting the metal blade isn’t enough. The chip side has to be handled too, and there are two main ways to do it.
Chip cloning
We read the chip in your working key and copy its data onto a new chip in the spare. The car sees the copy as your original key.
- Works on many older and mid-age transponder systems.
- Often quick, with no changes made to the car’s computer.
- The car treats both keys as the same key. If one is lost, it can’t be removed from the car by itself.
Onboard (OBD) programming
We connect professional diagnostic tools to the car’s OBD port and add the new key to the immobilizer as its own key.
- Needed for most smart keys, push-to-start fobs and many newer transponder systems.
- Each key is registered separately, so a lost key can often be deleted later.
- Some vehicles need a PIN code read first, or a module programmed on the bench.
Which method fits depends on the make, model, year and key type. We’ll tell you which one your car needs before we start.
What We Do On Site, Step by Step
- Confirm the vehicle and key type. On the phone we ask for year, make and model, and what your key looks like: plain blade, remote-head, laser-cut or push-to-start fob.
- Check proof of ownership. We look at your registration or title plus a photo ID before making any key.
- Cut the blade. We cut by code from the VIN where possible, or match your working key. Laser-cut (high-security) blades are cut on our mobile equipment.
- Program or clone the chip. We clone the transponder or program the new key through the OBD port, based on what the car supports.
- Program remote buttons. For remote-head keys and fobs, we set up lock, unlock and trunk functions.
- Test everything. We test the blade in the door and ignition, start the car, and try every button on both keys before we leave.
We do most cars on site, so there’s no need to tow to a dealer. For specific models, see pages like our Volkswagen Jetta key guide.
What Affects Time and Cost
We don’t quote a flat price, because copies vary a lot. These factors matter most:
- Key type. A basic transponder key is simpler than a laser-cut key or a smart fob.
- Cloning vs. programming. Cloning is often faster. Some cars need full OBD programming or a PIN code read.
- Make and model. Some brands have extra security steps or need bench work on a module.
- Key blank. Some fobs and blanks are harder to source than common ones.
- Time and location. Scheduled daytime visits are standard. After-hours work and travel distance can change the quote.

Most copy jobs are done in one visit. Simple clones often go quickly. Smart keys and cars that need PIN reading take longer. Our typical arrival time is 20–35 minutes in most of our area, depending on traffic and distance.
What to Have Ready
- Your working key or fob, plus any other keys you have.
- Registration or title and a photo ID with a matching name.
- The vehicle where we can reach it, ideally with room to open the driver’s door.
- The VIN handy. It’s on the driver-side dashboard near the windshield and on your registration.
- Year, make, model and trim when you call, plus a photo of your key if you’re unsure of the type.
We accept cash and credit card, and our technicians speak English and Spanish.
When a Copy Is Not the Right Service
A copy needs a working key. If your situation is different, one of these fits better:
- No working keys left: That’s an all-keys-lost job. See our car key replacement service.
- Keys locked inside the car: You need a car lockout service, not a new key.
- Key won’t turn, or the ignition is worn or damaged: A new key may not fix it. See ignition repair and replacement.
- Key broke off in the door or ignition: We extract the broken piece first, then make a new key if needed.
- A key was stolen: Cloning copies the old key, so a stolen clone could still start the car. Ask about programming new keys and removing the lost one where the car allows it.
