What Mercedes Mobile Auto Key Replacement Involves

Our Technicians' Advice
- Stay with the vehicle if it is safe to do so.
- If a smart key dies, look for a hidden metal blade inside it.
- Test the remote buttons and the trunk with the technician before we leave.
- Don't force a key that won't turn; check that the steering lock isn't engaged first.
Over Two Decades on Long Island
Our technicians are experienced locksmiths, not general handymen. Since 2001 Car Key Locksmith has focused on car keys and locks — and on coming to you.
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.
Understanding the Cost
Every job is quoted before a technician sets off — the price you hear is the price you pay. It depends on:
- The type of key (basic, transponder, remote-head, flip or smart key)
- Whether a working key is available or all keys are lost
- How many keys you want
Having the year, make and model ready helps us quote even faster. If anything changes once we see the job, we tell you before doing it.

Frequently Asked Questions
Is it cheaper than the dealer?
Usually, yes — and faster, because there is no tow, no parts order and no appointment. You get the price before we come out.
What should I have ready when I call?
Your location, the year, make and model, and your ID with the registration or title for when the technician arrives.
Do you repair remote head keys?
Yes. Honda and Toyota remote head repair is one of our most common jobs — a new shell, buttons or blade often costs far less than a new key.
Do you work weekends and holidays?
Yes. We work every day of the year, and the price is always quoted before we come out. Call (516) 750-0433.
Which areas do you cover?
All of Nassau County, much of Suffolk County and Queens, including JFK Airport, Jones Beach, Resorts World Casino and UBS Arena.
How much will it cost?
It depends on the vehicle and the key or lock involved. Call (516) 750-0433 with the year, make and model and we give you the exact price before we dispatch.
Can you replace a key for any car?
We carry keys and programming for most cars, SUVs, vans and pickups. Call with the year, make and model and we will confirm right away.
