Quick Answer
Okay, so here's the quick version if your keys got swiped. First, take a breath. Then, file a police report—you'll need it for insurance. After that, your next call is to a qualified mobile auto locksmith. Not the dealership, as they'll often require towing your vehicle and charge more. A good mobile locksmith will come to you, erase the stolen key from your car’s computer so it's useless, and then cut and program a brand new key and/or key fob right there. You're looking at anywhere from $150 for a simple chip key to $800, maybe more, for a fancy smart key/fob. The main thing is securing the car by deactivating the stolen key, which is the locksmith's priority.
Common Symptoms
Possible Causes
Step-by-Step Diagnosis
Step 1
Confirm the keys are truly stolen and not just misplaced. Do a thorough search of your home, car, and office before initiating expensive security procedures.
Step 2
Identify your key type (traditional, transponder, key fob, or smart key) as this is the biggest factor in replacement cost and procedure.
Step 3
Gather your vehicle's essential information: Make, Model, Year, VIN (Vehicle Identification Number), and your proof of ownership (license and registration/title). A professional will require this.
Step 4
Check if you have a spare key. If you do, you can drive the car, but you must still call a locksmith immediately to have the stolen key's code erased from the vehicle's computer system.
DIY vs Professional Costs
| Repair Type | DIY Cost | Professional Cost | Time Required |

Key Fob / Smart Key (Cut & Program) | Not feasible/recommended | $250 - $800+ | 45-90 min |
Emergency Mobile Service Fee | N/A | Add $75 - $200 | N/A |
When to Call a Professional Locksmith
- Call a professional immediately after confirming your keys are stolen to secure your vehicle.
- When you have no spare keys and are completely locked out or unable to start the car.
- For any vehicle made after the late 1990s, as it will require professional programming for a new transponder key, fob, or smart key.
- When you need to have the stolen key's code erased from your car's computer system, even if you have a spare.
- If you require immediate mobile service at your vehicle's location to avoid a costly tow to a dealership.
Prevention Tips
- Always be aware of where your keys are; don't leave them in plain sight or unattended in public places.
- Keep your spare key in a secure location inside your home, not in a magnetic box under the car.
- Consider separating your car and house keys to limit your losses if one set is stolen.
- When getting a new key, always demand that the locksmith erases the old, stolen key from the vehicle's memory.
- Never attach identifying information to your keychain that could link your keys to your car or home address.
