No working key does not always mean the vehicle must be taken to a dealership. For many compatible vehicles, Chicago Car Keys can use authorized vehicle information associated with the VIN to identify the correct factory key-cutting specification. Our mobile technician can then cut a replacement key at your location in Chicago or nearby Cook County suburbs.
How VIN-Based Key Cutting Works
- Verify the vehicle and ownership. We confirm the VIN, year, make, model, key system, government-issued identification, and acceptable ownership documentation before requesting or using vehicle key information.
- Confirm key-code availability. Authorized key-cutting information varies by manufacturer, vehicle age, and record availability. We also ask whether the door lock or ignition has ever been replaced because the VIN normally corresponds to the original factory key specification.
- Cut the mechanical key or blade. When compatible information and hardware are available, the technician cuts the traditional key, transponder-key blade, remote-head blade, or emergency insert blade to the applicable specification.
- Program and test when required. A correctly cut blade handles the mechanical portion of the key. Vehicles with an immobilizer, transponder, remote-head key, smart key, or push-to-start system may also require programming before starting. We test the applicable lock and ignition functions after cutting.
Factors That Affect VIN Key-Cutting Pricing
The quote depends on the vehicle year, make and model, key-code availability, blade type, replacement-key hardware, whether the locks still match the original VIN specification, programming requirements, and service location. We confirm the supported work and applicable quote before cutting begins.
When VIN Key Cutting May Help
- All original vehicle keys are lost
- An existing key is worn, bent, or damaged
- A replacement fob needs an emergency insert blade
- A key must be cut to the vehicle’s original specification

Frequently Asked Questions
Can you make a car key using only the VIN?
For many vehicles, the VIN and authorized records can help identify the original key-cutting specification. Ownership must be verified, and availability depends on the manufacturer and vehicle.
Will a VIN-cut key start my car?
A metal key may operate the lock or ignition mechanically, but vehicles equipped with an immobilizer usually require transponder or smart-key programming as a separate step.
What documents do I need?
Please prepare government-issued identification plus registration, title, or another document that connects you to the vehicle. We confirm the exact requirements when scheduling.
Can you cut the key at my location?
Yes, compatible keys can often be cut with mobile equipment at the vehicle after the required information and ownership documents are verified.
What if the ignition or door lock was previously replaced?
The VIN normally corresponds to the vehicle’s original key specification. If a lock was changed, the current lock may need to be decoded or serviced separately.
