24 Hour Mobile Auto Key Replacement Without the Wait

Many of our calls come from Holbrook, Miller Place and Medford.
Car Key Replacement: What We Do
- Spare keys cut and programmed at the same visit
- New keys cut from the VIN, a code or by decoding the lock
- Family and fleet spares made in one trip
- All-keys-lost situations handled — no original key needed
- Lost keys erased from the car's memory where supported
- Spare keys made at the same visit
What You Pay For
Here is what moves the price up or down:
- The make and model
- Whether a working key is available or all keys are lost
- The type of key (basic, transponder, remote-head, flip or smart key)
- How many keys you want
Call (516) 750-0433 with your year, make and model for an exact quote. It is usually less than the dealer, and there is no tow to pay for.
A Few Pointers
- Be careful with cheap online fobs — many are the wrong frequency for your car.
- Get a spare made while you still have a working key — it costs far less than an all-keys-lost call.
- Stay with the vehicle if it is safe to do so.
- Note where you are parked — a cross street or landmark helps us find you fast.

For 24 hour mobile auto key replacement in Riverhead, the visit looks like this:

Frequently Asked Questions
Do I need to bring the car to you?
No. We are a mobile locksmith: the technician comes to your car at home, at work or at the roadside.
Do you repair ignitions?
Yes — ignition repair and replacement, including Honda and Acura ignitions that wear out and stop turning.
What if I have lost every key and have no spare?
We can still make a new key. With your ID and the registration or title, we originate a key from the VIN or the locks and program it to the car.
Can you cut laser cut keys?
Yes. We cut laser cut (sidewinder) keys on site, including Honda, Acura, GM, Toyota and Lexus laser cut keys, and program them to the car.
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.
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.
Is replacing a car key cheaper than going to 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.
How long does it take?
Most key replacements and programming jobs are finished within an hour of arrival. We tell you what to expect when you call.
