Acura TL key types & programming facts
From 2000–2008, Acura TL keys use a transponder system that must be programmed to the vehicle’s immobilizer with professional diagnostic equipment or approved on‑board procedures, depending on the year. Starting in 2009, many TL models use a smart key/proximity system where both the fob and its emergency key blade must be programmed to the vehicle, typically via OBD with specialized tools. Remote lock/unlock functions also require matching the correct FCC ID/key type to the vehicle and programming it to the car’s body control module.
Key types used on the TL:
- transponder chip key with separate remote (2000-2003)
- remote-head key (integrated key and remote) (approx. 2004-2008)
- smart key / proximity key with emergency insert (push-to-start models) (2009-2014)
Common fob FCC IDs: KOBUTAH2T, K0BUTAH2T, M3N5WY8145, MLBHLIK-1T, MLBHLIK1T — check the back of your fob; we confirm the exact variant on site.

How we validate this guide
Year coverage comes from our consolidated vehicle programming dataset. Route-level programming status is reviewed against internal route sheets and available manufacturer, security-access, and professional tool references. Exact button sequences are marked source-verified only when we have year/equipment-specific support; where a year is labeled “route verified, steps vary,” we confirm the exact fob, trim, and prompts before programming.

Common questions
Can I program an Acura TL key or fob myself?
Some earlier TL remotes can be programmed with on-board procedures, but most transponder and smart keys require professional locksmith or dealer equipment connected through the OBD port.
Do I need a specific FCC ID for my Acura TL remote or smart key?
Yes. The replacement remote or smart key must match the original’s FCC ID and frequency, such as KOBUTAH2T for 2000 TL or M3N5WY8145 for 2009–2014 smart keys.
Does a new Acura TL key need more than cutting?
Yes. In addition to cutting, the transponder or smart key chip must be electronically programmed to your TL’s immobilizer and remote system for the car to start and the buttons to work.
Can you program a TL key fob without going to the dealership?
For most years, yes - the route is onboard relearn or an OBD tool, both of which a mobile locksmith handles at your location.
Does this program the remote only, or the transponder key too?
It depends on your key type. Tell us your FCC ID and we will confirm.
What if my year says professional programming required?
Those years need a programmer or security access; we bring the tool to you and program it on site.
How much does it cost?
It depends on year, key type, and whether you have a working key. Call (833) 439-8636 for a firm price before we dispatch.
