Covered on Every Call
On a typical visit we can:
- Remote and smart key spares paired with the car
- Valet keys that open the doors but not the trunk or glovebox, where available
- Several spares at once for family members and fleets
- Spare keys cut to match your working key exactly
- Work done at your car — at home, at work or at the roadside
- Transponder chips programmed so the spare actually starts the car
The Price Comes First
No two jobs are identical, which is why we quote each one on the phone first. The main factors:
- How many spares you want
- Whether the key needs programming as well as cutting
- The type of key being copied (basic, transponder, remote-head or smart key)
Compared with the dealer, most drivers save both money and time — and skip the tow. Call (516) 750-0433 for an exact quote — it takes a minute.
What Happens When You Call
No surprises — this is how it goes:

- We quote the spare and an arrival time.
- The technician cuts the new key from your working key and programs it.
- You test the spare in the doors and the ignition before we leave.
