Car Key FAQ
How long does it take to get a new car key?
Most standard keys and transponder keys are cut and programmed on-site during the same visit. Smart keys and proximity fobs may take longer depending on the vehicle's security protocol. We carry a massive inventory of key blanks and fobs so you rarely have to wait for parts.
Can you make a key if I lost all my keys?
Yes. We can generate a new key using your vehicle's VIN (Vehicle Identification Number). We'll need your registration and photo ID for verification. Once we cut the key by code and program it to your car's immobilizer, any previously lost keys are deactivated for security.
Do you program smart keys and push-to-start fobs?
Absolutely. We have advanced diagnostic programmers that handle most smart key systems, including Toyota Smart Key, Honda Smart Entry, Ford Intelligent Access, Nissan Intelligent Key, BMW Comfort Access, and more. No dealership visit required.
Is it cheaper than the dealership?
Our mobile service comes to your location, so there is no tow truck needed. We use OEM-quality or genuine OEM parts depending on your preference. Call us at (209) 554-5627 for a free upfront quote so you know exactly what to expect before we start any work, or fill out our online form and we will get right back to you.
What if my key broke off in the ignition?
We extract the broken key fragment using specialized extraction tools, then cut and program a new key. If the ignition cylinder itself is damaged, we can replace it and match the new cylinder to your existing keys or provide new ones.
Do you cover European luxury cars?
Yes. BMW, Mercedes-Benz, Audi, Porsche, Land Rover, Jaguar, Volvo, and Mini are all within our capabilities. European vehicles often have more complex security systems, but our technicians have the training and equipment to handle them. Call us at (209) 554-5627 or use our online form for a free, no-obligation quote on your specific vehicle.
