You need a new car key. Maybe you lost your only copy, the fob stopped working, or the key snapped in the ignition. You have two main options: call a locksmith or go to the dealership. Both can get you a working key, but they differ significantly in cost, speed, and convenience -- especially in New York City, where towing a car to a dealership is expensive and time-consuming.
This guide breaks down the real differences so you can make the right choice for your situation. If you need a key right now, call (718) 412-1332 for immediate automotive locksmith service.
Cost is usually the biggest factor. Here is how the two options generally compare for common key types in the NYC area. These are approximate ranges -- actual prices vary by vehicle make, model, and year.

If your key fob has stopped working, the issue may be a dead battery rather than a failed fob -- a locksmith can diagnose this quickly.

In a city where getting around is already complicated, the logistics of key replacement matter. Here is how the two options differ:
Some drivers worry that using a locksmith instead of a dealership will void their car warranty. This is a myth. The Magnuson-Moss Warranty Act prohibits manufacturers from requiring you to use only dealer services to maintain warranty coverage. As long as the key is properly cut and programmed to manufacturer specifications -- which a qualified automotive locksmith will do -- your warranty remains intact.

In most cases, yes. Locksmiths typically charge less for the same service because they have lower overhead than dealerships. The savings are most significant for transponder key programming and basic key cutting. However, for certain luxury or high-security vehicles, the dealership may be the only option.
Yes. Automotive locksmiths carry professional programming equipment that can program transponder chips for most vehicle makes and models. They can do this at your location rather than requiring you to tow or drive the car to a dealership. Some newer vehicles with proprietary encryption may require dealership-only programming.
A mobile locksmith can typically cut and program a new car key in 30 to 90 minutes at your location, depending on the key type and vehicle. Basic key cutting takes minutes, while transponder programming and key fob setup take longer. A dealership may require days if the key needs to be ordered.
Many automotive locksmiths can program replacement key fobs for push-to-start systems, though this depends on the vehicle make, model, and year. Some newer vehicles with rolling encryption require dealership programming. Call a locksmith first to ask if they can handle your specific vehicle.
If you have no working key at all, a locksmith can still help. They can cut a new key by reading the lock, then program the transponder from scratch. This is called origination and costs more than duplicating an existing key, but it is still typically less expensive and faster than having a dealership do the same work.
No. Under the Magnuson-Moss Warranty Act, a manufacturer cannot void your warranty simply because you used a third-party service provider for key replacement. The key must be properly cut and programmed to manufacturer specifications, which a qualified automotive locksmith will do.
