Losing the key to your Nissan Altima is stressful, especially when it is your daily driver. Whether you have misplaced your only key, broken a bladed key, or want a spare before something goes wrong, we handle it where your car is parked. Crenshaw Lock Company has served Greater Los Angeles and Ventura County since 1987, and we are fully mobile. There is no shop to tow your car to.

The Altima covers a wide range of model years from 2007 through 2024, and the key system changed over that time. The exact key, chip and programming depend on your trim and VIN, so we confirm the correct key by VIN before any cutting or programming begins. That avoids buying or cutting the wrong key for your car.

We cover both situations: adding a spare when you still have a working key, and making a new key when all keys are lost. A spare is usually simpler and more affordable than starting from nothing, so do not wait until your last key is gone.

Nissan Altima key systems by year

Earlier years

Earlier Altimas generally use a bladed transponder key, a metal key with a plastic head that holds an anti-theft chip, and many trims also offer the Nissan Intelligent Key proximity system. A bladed key must be cut to match your locks and have its chip programmed so the engine will start. Intelligent Key versions use a fob that the car senses nearby. Which system your car has depends on trim, so we confirm the correct key by VIN before cutting or programming. This can be done at your vehicle, including when all keys are lost.

Recent years

Recent Altimas generally use an Intelligent Key proximity fob with push-button start on most trims. You keep the fob in a pocket or bag, and the car detects it to unlock and start. These fobs usually include a hidden emergency blade for the door. Replacement involves supplying a compatible fob and programming it to the car. The exact fob and procedure depend on trim and VIN, so we verify by VIN first. We perform this on-site, whether you need a spare or have lost every key.

Exact key, chip and programming vary by trim and VIN — we confirm the right key for your car before cutting.

How we replace your key

  1. 1

    Call and describe the situation

    Call (323) 997-8867 and tell us your Altima's year, whether you have any working key, and where the car is parked. We are available 24/7.

  2. 2

    We come to your vehicle

    Our technician drives to you anywhere in our service area. We are mobile only, so the work happens at your car.

  3. 3

    Verify ownership and VIN

    We check your photo ID and proof of ownership and read the VIN. The VIN lets us confirm the correct key for your trim before we cut or program anything.

  4. 4

    Cut and program the key

    We prepare the correct bladed key or Intelligent Key fob for your car and program it so it works with the vehicle. For all-keys-lost, this is done without an original key.

  5. 5

    Test everything

    We test locking, unlocking and starting, and any spare, so you leave with keys that work reliably.

What to have ready

  • Proof of ownership, such as registration or title
  • Government-issued photo ID matching the ownership record
  • The VIN, found on the dashboard near the windshield or on the door jamb sticker
  • Any existing keys or fobs, including broken ones, if you have them

What affects the price

  • Whether you need a spare key or are in an all-keys-lost situation
  • Bladed transponder key versus Intelligent Key proximity fob
  • Your Altima's model year and trim, confirmed by VIN
  • Whether a bladed key needs cutting in addition to programming
  • Time of day and your location within the service area

Nissan Altima keys — FAQs

What if I lost all my Nissan Altima keys?
We can make a new key at your vehicle even with no original. We verify ownership and confirm the correct key by VIN, then cut and program it. Call (323) 997-8867 any time, day or night.
Can you make a spare Altima key?
Yes. Adding a spare while you still have a working key is typically simpler than all-keys-lost. We confirm the right key by VIN and program it on-site.
Do I need my original key to get a replacement?
No. We can create a key without an original, after verifying your ID and proof of ownership. Having a working key just makes the process simpler.
What is the difference between a push-button and a bladed Altima key?
A bladed transponder key is inserted into the ignition and has a cut metal blade. An Intelligent Key is a proximity fob that works with push-button start. Which one your car uses depends on trim and VIN, so we check before proceeding.
Which key does my Altima use?
Earlier years generally use a bladed transponder key, with Intelligent Key available on many trims. Recent years generally use an Intelligent Key fob on most trims. We confirm the exact key by VIN.
What do you need to make a key?
We need photo ID, proof of ownership, and the VIN. With those, we can confirm the correct key and proceed at your vehicle.
Do I have to tow my Altima to you?
No. We are fully mobile and come to wherever your car is parked. We have no shop, so no towing is needed.
