2017 Nissan Altima Key Fob Programming

Updated 2026 Programming, battery & replacement fob

The 2017 Nissan Altima key fob can't be programmed at home — it needs a locksmith or dealer with a diagnostic tool. Below is the exact replacement fob you need (FCC ID and part number) and what to expect.

Professional programming required

This remote can't be programmed with a do-it-yourself procedure. The vehicle needs a diagnostic tool connected to its OBD port to pair a new remote, so a replacement has to be set up by an automotive locksmith or a dealer.

Order the correct replacement remote below — match the FCC ID on your current fob first — then have a local automotive locksmith or the dealer program it to your vehicle.

Replacement key fobs

Find your key type below, then match the FCC ID printed on the back of your existing fob — or, for a plain transponder key, the blank code — to be sure of the right part.

Proximity Key

Stays in your pocket — the car unlocks and starts without inserting a key.

2017 Nissan Altima key fob battery

Your 2017 Nissan Altima key fob uses a CR2032 3V lithium coin cell. A fresh one typically lasts 3–5 years.

How to replace the battery

  1. 1 Slide the release latch and pull the metal emergency key out of the fob.
  2. 2 Use that key (or a coin) to pry the two halves apart at the seam.
  3. 3 Lift out the old coin cell — note which side faces up.
  4. 4 Drop in the new battery the same way (printed + side usually faces the back cover).
  5. 5 Press the case back together until it clicks, then test lock/unlock and push-to-start.

Battery tips

  • Use a fresh, name-brand 3V lithium cell — bargain cells drain quickly.
  • Even with a dead fob battery you can usually still start the car by holding the fob against the start button — check your owner's manual.
  • If the fob still won't work after a new battery, it may need re-syncing or programming.
