Question 1

My insert key snapped in the ignition of my 2011 RL. Can you get the broken piece out?

Accepted Answer

Yes. On the 2011 RL, the ignition cylinder hides behind the ignition switch cover, and the metal insert key (35111-SJA-305) is what physically turns it during emergency starts. If that blade breaks off inside, I use extraction tools built for Honda/Acura high-security cylinders so the internal wafers stay intact.

Once the fragment is out, I cut a fresh insert key and confirm it turns smoothly in both the driver door cylinder, which sits behind a cap on the handle, and the ignition. If you need a full replacement remote registered to the immobilizer at the same time, I handle that on site too.

Question 2

What kind of key system does a 2011 Acura RL actually use?

Accepted Answer

Not a basic metal transponder key. The 2011 RL uses Acura's Keyless Access system from the second-generation platform (KB1/KB2 chassis, 2005 through 2012). The proximity remote handles lock, unlock, trunk, and panic while also carrying the immobilizer transponder, a Philips ID46 (PCF7936) chip.

Acura lists the fob assembly under part numbers 72147-SJA-A01 and 72147-SJA-A11 across the 2011 trims, including RL, RL Technology, RL Advance, and the SH-AWD variants. The metal insert key opens the car and turns the ignition, but the engine will not start unless the embedded transponder has been properly registered to your RL's immobilizer module.

Question 3

My RL says KEYLESS REMOTE NOT DETECTED. What should I try first?

Accepted Answer

Start with the batteries. This remote uses two CR2025 cells stacked together, and a lot of owners replace one and leave the other one fading. When voltage drops, the dash typically shows "KEYLESS REMOTE LOW BATTERY" before escalating to the full "KEYLESS REMOTE NOT DETECTED" warning.

Quick checklist:

1. Replace both CR2025s and check that the battery contacts inside the fob are not bent flat.
2. Make sure the remote is fully inside the cabin. Passing it through an open window or holding it near the doorframe can confuse the interior antennas.
3. If the message pops up while driving, do not shut the car off somewhere risky. The engine keeps running, but it will not restart once you turn to LOCK unless a recognized remote is back inside.

Question 4

Can I buy a 2011 RL remote online and program it myself to save money?

Accepted Answer

No. The 2011 RL's Keyless Access system requires professional diagnostic equipment connected through the OBD-II port to register a new remote to the immobilizer. There is no owner-level self-programming procedure on this platform, no key-turn sequence, no hold-this-button-and-wait trick. That only applies to some older Honda models with basic transponder keys, which is a completely different setup. If you already bought a remote online, bring it along. As long as it matches the right FCC ID and board number, I can program it on site and save you from buying another one.

Question 5

The door handles on my 2011 RL stopped sensing the key for proximity unlock. Is the fob bad?

Accepted Answer

Not necessarily. This is a common complaint on the 2005 through 2012 RL. Acura issued TSB 09-019 addressing keyless access antenna issues and intermittent detection problems on this chassis. The door handle sensors and their wiring degrade over time, especially the driver side. If trunk release or engine start still recognizes the fob, the remote itself is fine and the problem is on the car's antenna side, not in your hand. Swapping batteries is still worth trying first, but if only one handle acts up while everything else works, the fob is not your issue.
