Frequently asked questions
What proof of ownership do I need to provide for a Chevrolet key replacement?+
When our technician arrives, you will need to show a government-issued photo ID (driver's license or passport) and proof that the vehicle is registered or titled in your name. Your vehicle registration card or title document works perfectly. Having your VIN number ready — found on the dashboard near the windshield or on your registration — also helps speed things up. If you are managing a fleet vehicle or acting on behalf of a family member, call (347) 474-0837 ahead of time and we will tell you exactly what documentation applies to your situation. We verify ownership on every job, no exceptions.
Can you replace a Chevrolet Blazer EV key fob on-site, or does it need to go to a dealer?+
Yes, we handle Chevrolet Blazer EV fob replacement and programming on-site. The Blazer EV uses a proximity-based smart key system with rolling-code encryption, which our mobile programming equipment is built to handle. You do not need to tow the vehicle to a dealer. Our technician comes to your location anywhere on Staten Island, programs the replacement fob to communicate correctly with your vehicle's body control module, and verifies full functionality before leaving. The entire process is done at your car's location — no dealership appointment, no tow truck required.
What factors affect the price of a Chevrolet key replacement?+
Several variables determine the final cost. The most significant are the specific Chevrolet model and model year, since different vehicles use different key technologies that require different tooling and blanks. The type of key — basic transponder, remote head key, or proximity smart key — also plays a large role. Time of day matters for emergency overnight calls. Travel distance to your location within Staten Island is factored in, and whether physical replacement parts such as a new key blank, fob shell, or battery are needed affects the total as well. We confirm an exact up-front price before any work begins, so you always know what you are agreeing to.
How long does an on-site Chevrolet car key replacement typically take?+
For the majority of Chevrolet models, our technicians complete the key cutting and transponder or fob programming in a single visit, often within 30 to 60 minutes of arriving at your location. More complex situations — such as a complete key loss on a newer smart key system where no working key exists for the vehicle — may take longer because the programming process requires additional steps to enroll a new key from scratch. We will give you a realistic time estimate when you call, and our technician will keep you informed throughout the process.
I locked my keys inside my Chevrolet Blazer. What should I do while I wait for you?+
First, check whether any other door, the trunk, or a rear window is accessible — sometimes a second entry point is open. If you have a spare key at home or with a trusted person nearby, that is always the quickest resolution. Do not attempt to force entry yourself or use improvised tools on the door or window, as this risks damage to your vehicle's seals, trim, and electronic components, which can be expensive to repair. Stay somewhere safe and visible, especially at night. Call (347) 474-0837 and our technician will come to you. Going forward, having a spare programmed key made while the original is in hand is the single most effective way to avoid a future lockout.
Do you make spare Chevrolet keys, or only replacements when all keys are lost?+
We do both. In fact, having a spare key made while you already have a working key is faster and often simpler than a full lost-key replacement, because the existing key helps the programming process. If you have one working Chevrolet key and want a backup — a smart move given how costly a future lockout can be — call (347) 474-0837 and we can schedule a mobile visit to your home or workplace anywhere on Staten Island. We cut and program the spare on-site, verify it works correctly with your vehicle, and you walk away with a fully functional second key.
