24 Hour Mobile Auto Key Replacement in Greenvale: What We Do
Since 2001 we have learned that drivers want three things: a fair price, a realistic arrival time and work that lasts. That is how we approach car key replacement in Greenvale.
The technician checks ownership, explains the options and gets to work at your car.
The Price Comes First
We quote every job upfront on the phone, so you know the price before anyone is dispatched. What the price depends on:
- The make and model
- Whether a working key is available or all keys are lost
- How many keys you want
- The type of key (basic, transponder, remote-head, flip or smart key)
What We Take Care Of
- All-keys-lost situations handled — no original key needed
- Spare keys made at the same visit
- Lost keys erased from the car's memory where supported
- Night, weekend and holiday calls, with the quote always given first
- New keys cut from the VIN, a code or by decoding the lock
- Keys tested in the doors, ignition and trunk before we leave
Serving Nassau County Since 2001
Car Key Locksmith opened in 2001. Today our vans cover Nassau County, much of Suffolk County and Queens, still with the same mobile, upfront approach.
When you have been doing something since 2001, you learn what matters: showing up when you said you would, quoting fairly, and testing everything before you leave.
Smart Habits
- If a smart key dies, look for a hidden metal blade inside it.
- If a key breaks in the lock, leave the piece in and call us rather than digging at it.
- Test the remote buttons and the trunk with the technician before we leave.

Whatever you drive, there is a good chance we have the key. We work on Mercedes-Benz, Jeep, Honda, Acura, Mazda and Jaguar — and many more — including basic metal keys, remote-head keys, flip keys and transponder chip keys.
