2012 Acura RL
Trusted by 1,000+ Customers in Ventura County

Q: Do I need to tow my 2012 Acura RL to the dealer if I have no keys?

No. If the RL is in Downtown Ventura and the battery has enough power for diagnostic communication, I can handle all-keys-lost on site. The dealer route usually means a tow plus waiting on parts and a service slot. Also, some dealers refuse to program certain aftermarket transponder blanks even if they cut correctly. I match FCC ID, IC number, and memory type before programming so there’s no guesswork.

Q: How long does an all-keys-lost replacement take on a 2012 Acura RL?

Plan on about an hour. The actual registration with the HDS-type tool is quick. Most of the time goes into real-world steps: getting the car open, cutting the HD103/HO03 insert, and running full function tests. Before I leave, I confirm touch entry, button operation, trunk release, panic, one start, shutdown, and restart. On these RLs, testing is what separates a programmed key from a proven key.

Q: My RL shows “CHECK KEYLESS ACCESS SYSTEM” and touch unlock quit. What usually fails first?

That warning isn’t just a fob battery issue. The RL system monitors door-handle touch sensors and multiple low-frequency antennas that detect the remote. Key components include the Smart main unit (38320-SJA-A03) and interior LF antennas like 38387-SJA-003 (center panel) and 38388-SJA-003 (console). A common failure is the front outer door handle sensor. Service Bulletin 08-059 links no-unlock-by-touch to water intrusion damaging the handle circuit. If I see DTC B1660, that points to the front interior LF antenna circuit (open/short), not the remote itself.

Q: Can you make a spare at the same time so I have two keys?

Yes, and we strongly recommend it. Honda and Acura immobilizers are programmed in sessions where all keys must be present. Any key not introduced during the session will be erased from the system. That means adding a second key while we are already connected costs less than calling us back for a separate visit later. On some newer Acura models like the ZDX, the service manual requires a minimum of two keys to be programmed during an AKL session. If you just went through all-keys-lost, the last thing you want is to be in that situation again. Get the spare now.

🔧 PRO TIP

2012 RL is the RL-TEC setup, so it’s Smart Entry keyless access with the ACJ8D8E24A04 remote. The board/IC marking that matters is 216J-EUE24A04, and many listings show CR2025 x2. That’s why swapping only one coin cell can still cause short range or random lock behavior. Match FCC and IC first—frequency claims bounce between 312–315 MHz depending on the source.

2012 Acura RL Transponder key Replacement - Fast, Affordable & Professional

In Downtown Ventura I got a call for a 2012 Acura RL where the key worked, but the car kept acting like it belonged to the other driver.

Every unlock was triggering the wrong seat and mirror memory, and the MID would flash the wrong Driver ID. He flipped the remote over and pointed at the big “1” on the back like the car was ignoring it on purpose.

Acura has a quick relink trick: ignition to LOCK, press UNLOCK on the remote, then ignition to ON and check the MID again. We did it right there, and the Driver ID finally matched the remote label.

He only had one working insert key, so I cut him a spare (35111-SJA-305) and registered it properly so he wasn’t stranded if the original went missing.

The human moment was him watching me pop the ignition knob cover and reveal the hidden key cylinder. He’d never seen it. Once he realized there’s still a mechanical side under the smart system, the whole car felt less mysterious and a lot more manageable.

“Tim is a hero. He programmed a master proximity key for a newer Volkswagen that multiple locksmiths refused to touch. He spent hours until late at night making sure every function worked perfectly. The skill level here is incredible.”

Lost Your Acura RL Key? Here's What to Know

What to expect when we arrive

I lost every keyless remote for my 2012 Acura RL. Can you make a new one?▼

Yes. The 2012 RL uses a Smart Entry remote plus an insert blade tied to the immobilizer. OEM remotes are Memory No.1 (72147-SJA-A01) and Memory No.2 (72147-SJA-A11), FCC ID ACJ8D8E24A04. The insert key is 35111-SJA-305 and uses a Philips ID46 chip. For an all-keys-lost job I verify ownership, gain entry, cut the insert, register the new remotes, and erase the missing IDs so any lost fobs can’t start the car later.
