Automotive locksmith services
Everything from a simple lockout to rebuilding the key data in a car's computer.
Lost all keys
No working key left? We make a new one from scratch, cut it to the lock and program it to the car, so you're not stuck towing to a dealer.
Spare and duplicate keys
Adding a spare while you still have one working key is the simplest key job there is. Don't wait until you're down to the last one.
Key fobs, remotes and smart keys
Remote programming for flip keys, remote-head keys and push-to-start smart keys.
Car lockouts
Keys locked inside or trunk won't open. We come out 24/7 and get you back in.
Ignition repair and replacement
Key won't turn or won't come out. We repair or replace the ignition, including Mercedes ignition (EIS) repair.
Module programming
When an immobilizer, body or engine module fails or gets replaced, the keys stop working. We program it at the car, or you can mail the module to Duvall's Auto Lab instead.
Car lock repair and rekeying
Door and trunk locks that stick, break or need to match a new key.
Diagnostics and remote starters
Computer diagnostics for key and immobilizer problems, and remote starter installation.
OEM or aftermarket, your choice
We carry both. An OEM key matches what the dealer sells. An aftermarket key usually costs less. We'll give you both options for your car before we start.
We specialize in lost-key jobs on luxury and European cars, which most locksmiths send to the dealer, and we handle many other makes too.
And many others. Mercedes ignition repair and key repair too.

Common questions
Something else? Call 201-400-4659.
I lost every key to my car. Can you make a new one?
Yes. Lost key generation is one of our specialties. We make the key from scratch, cut it to the car and program it to the car's computer, including BMW, Volkswagen, Mercedes-Benz, Audi, Porsche, Volvo and Saab.
Do I need to tow my car to the dealer?
No. We come to wherever the car is and make the key there. For a few cars the module has to come out and be programmed on our bench, and we'll tell you up front if yours is one of them.
Do you program key fobs, remotes and push-to-start keys?
Yes. We program remotes, flip keys and push-to-start smart keys, and we offer both OEM and aftermarket keys.
What do I need to show you?
Photo ID and the registration or title for the car. We check that the car is yours before we open it or make a key.
My car isn't near New Jersey. Can you still help?
For key programming and module repair, yes. Mail the module to Duvall's Auto Lab and we send it back ready to install, typically within 1 to 3 business days.
