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 a selected nearby community.
VIN-based key cutting is especially useful when every key is lost, the original key is too worn to duplicate accurately, or a replacement blade must match the vehicle’s existing locks. Before service, we verify the vehicle identification number, the customer’s government-issued identification, and proof of ownership. We also confirm the year, make, model, and key system because VIN availability and code access vary by manufacturer and vehicle age. A correctly cut blade addresses the mechanical portion of the key. If the vehicle uses a transponder, remote-head key, smart key, or push-to-start system, programming may also be required before the vehicle will start. We explain those requirements before work begins and test the new key in the applicable door lock and ignition after cutting.
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.
