2010 Acura TSX
Lost Key Recovery Service in Ventura County

Q: Is a mobile locksmith actually cheaper than the Acura dealer for a 2010 TSX key?

In most cases, yes. Dealer process usually means ordering a VIN cut retractable key, scheduling service, and using HDS immobilizer functions that require security password retrieval before keys can be added. The car has to be on their lot. I perform the same immobilizer workflow, but I am mobile and the job stays with one technician from start to finish. In Camarillo, that often eliminates towing and waiting room time.

Q: Does your TSX key service include cutting the blade and programming the immobilizer chip?

Yes. On a 2010 TSX flip key, the sidewinder blade must be cut to match your locks and the transponder must be registered so the engine will continue running. After immobilizer programming, I sync the four remote buttons and verify lock, unlock, trunk, and panic before I leave. If your flip shell is broken but the electronics still work, I can often transfer your original board into a fresh case and complete programming so the car recognizes it correctly.

Q: My TSX flip key blade will not stay locked open. Is that a known issue?

Yes. Acura issued Service Bulletin 10 008 covering retractable master keys that fail to lock in the extended position. The cause is wear at the release button and collar from repeated use. The repair is replacing the key case, cutting the new blade, and confirming immobilizer registration. For TSX sedan, key case part numbers are 35120 TL0 307 for Driver 1 and 35120 TL0 308 for Driver 2. Acura lists operation 1161D3 with a 0.4 hour flat rate time and references failed part 72147 S0K A23.

Q: I replaced the CR1616 and the remote still will not lock or unlock. What now?

First confirm it is a CR1616 installed with correct polarity. Acura lists the coin cell as 72148 S0A 000. Next inspect the battery clips and inner cover tabs. A slightly bent contact can make the remote act completely dead. If the ignition re sync routine never triggers a door lock response, the issue is likely inside the remote board or contact pads. If the car still starts normally, your immobilizer chip is fine. This is strictly a remote transmitter problem.

2010 Acura TSX Remote flip key Replacement - Fast, Affordable & Professional

In Camarillo, in the Ventura Boulevard shopping area, a TSX owner walked out to his 2010 and did the pocket pat twice. Nothing.

He had lost the only flip key. Doors locked. No spare. No easy solution that did not involve a tow and a dealership calendar.

First thing I did was confirm ownership and identify the system. This TSX runs the retractable master key with integrated immobilizer. That means two jobs every time. Cut the high security blade. Register the transponder so the engine actually stays running.

I opened the driver door cleanly, set up at the car, and connected through the OBD port. With all keys lost, the immobilizer has to be accessed and rewritten properly. I programmed a fresh MLBHLIK 1T flip key, then cut the blade to match the locks.

Then came the boring truth loop. Start. Let it idle. Shut it down. Restart. Lock. Unlock. Trunk. Panic.

No warning lights. No stall after one second. Just a normal TSX again.

He looked at the key like it might disappear too. Then he drove off from the same parking spot instead of waiting on parts and a service lane.

2010 Acura TSX Pricing Questions

Pricing, process, and what's included

How much is a replacement flip key for a 2010 Acura TSX, cut and programmed on site?▼

It depends on whether you still have a working key. Adding a spare is faster because I can clone the mechanical cut and simply register the new transponder. All keys lost takes more time because I am cutting from scratch and performing a full immobilizer registration. Your 2010 TSX uses flip key 35113 TK4 A00 for Driver 1 or 35113 TK4 A10 for Driver 2 with FCC ID MLBHLIK 1T and an ID46 transponder. That start side requires proper diagnostic programming, not an ignition cycling trick. Call and I will quote your exact setup.
