| Question | Answer |
|---|---|
| Typical cost | Typical total cost is $180-$450 (USD), depending on TSX sedan year, key type, whether programming is needed, and whether all keys are lost. Canadian customers pay the equivalent in CAD. |
| Programming required? | Often yes for TSX sedan transponder keys and remote keys; the exact programming route varies by year and is confirmed for your vehicle during dispatch. |
| All keys lost? | Often serviceable on-site after valid ID and proof of ownership are verified, then a new key is cut and enrolled to the Honda/Acura immobilizer when compatible. |
| Online fob accepted? | Sometimes. The TSX sedan is picky about part numbers and lock-state; we check compatibility before attempting to program a customer-supplied remote or key. |
| What to prepare | TSX sedan year, your location (USA state or Canadian province), government-issued ID, proof of ownership, and whether you still have a working key. |
Replace a lost or damaged TSX sedan key, then verify start and lock functions before closeout.
Enroll a new key to the Honda/Acura immobilizer when compatible, and confirm it starts and runs.
Troubleshoot dead buttons, worn shells, and intermittent remotes on TSX sedan key sets.
If the TSX sedan key won’t turn or sticks, ignition wear may be the real problem.
Non-destructive entry when keys are locked inside the TSX sedan.
Remove a snapped key blade from the TSX sedan door or ignition without damaging the lock.
Some TSX sedan owners already have a key blank or remote fob in hand. That can work, but only when the exact chip type/FCC ID and lock-state are compatible with your model year. If you bring your own part, we’ll confirm compatibility before attempting cutting or programming.
Transponder-style replacement key option commonly associated with TSX sedan immobilizer systems.
Remote fob option; exact pairing compatibility depends on TSX sedan year and original remote type.
Model-focused help for pairing a TSX sedan remote or integrated remote key when supported.
The TSX sedan sold in the 2004-2014 range is typically secured by a Honda/Acura immobilizer that expects a correctly coded transponder key. Many years also use a separate remote fob or an integrated “remote key” where the blade and remote share one unit. Because markets and trims vary across the USA and Canada, the exact key part is confirmed before service.
Mechanical turning component; wear here can prevent the TSX sedan key from turning smoothly.
Where the cut key blade must match; damage or prior re-keying changes what “fits.”
Often overlooked until the TSX sedan needs manual access; a correct blade cut matters.
Vehicle-side receiver that listens for lock/unlock commands from a compatible remote.
Can bind when the wheel is under load; this can feel like an ignition problem.
| Option | Best for | Watch out for |
|---|---|---|
| Acura dealership | OEM parts and dealer records | Towing, appointments, higher total cost |
| Mobile locksmith | Lost keys, spare keys, no-tow situations | Requires ID, ownership proof, compatible parts |
| Online fob | Possible savings when exact part is known | Used/refurbished fobs may be locked or incompatible |
| DIY programming | Add-a-key for older mechanical/transponder | Not suitable for all-keys-lost or immobilizer resets |
If the TSX sedan remote won’t lock/unlock but the key starts the car, it’s usually a remote-side issue (battery, remote damage, or mismatch). If the key turns but the engine won’t run, the immobilizer/transponder side is more likely.
Aftermarket keys and fobs can be viable, but the TSX sedan is sensitive to chip type and remote specs. We’ll confirm whether your part can be enrolled before investing time cutting/programming.
These year bands describe what the TSX sedan typically uses. Exact key type can vary by trim and market in the USA and Canada, so the final match is confirmed before service.
| Years (context) | Key system (typical) | Notes |
|---|---|---|
| 2004-2008 (early TSX sedan) | Honda/Acura immobilizer + transponder key; separate remote common | Typical identifiers in the data set include transponder chip ID46 and remote FCC ID OUCG8D387HA (varies by year). Programming route is confirmed for your vehicle. |
| 2009-2014 (later TSX sedan) | Honda/Acura ID46 (PCF7936) era; integrated remote key common | Typical identifiers in the data set include chip PCF7936 and FCC ID MLBHLIK1T (varies by year). Add-a-key vs all-keys-lost procedures can differ. |
For a TSX sedan, the main price drivers are whether you still have a working key, whether immobilizer enrollment is required, and whether the remote portion is part of the same key or a separate fob. Lock and ignition condition also matters, especially if the key won’t turn or the cylinder has been replaced before.
Typical cost is $180-$450 (USD) for TSX sedan key work, presented as industry-typical and confirmed at dispatch. Canadian customers pay the equivalent in CAD.
| Factor | Cost impact |
|---|---|
| Spare key with one working key | Usually lower because the TSX sedan can often be added as an “add-a-key” scenario. |
| All keys lost | Usually higher due to additional steps to originate a key and enroll it to the immobilizer. |
| Customer-supplied fob | Depends on compatibility, condition, and whether the remote is already locked to another vehicle. |
| Emergency timing or remote location | May affect service call cost (distance, access constraints, and scheduling). |
| Vehicle-side issue (battery, ignition) | May require diagnosis before key work if the TSX sedan won’t communicate or won’t turn. |
Final pricing is confirmed after the TSX sedan year, key type, location, authorization, and compatibility are reviewed.
For a TSX sedan, this commonly involves originating a cut key and enrolling a transponder to the Honda/Acura immobilizer after ownership is verified.
If the TSX sedan cranks but won’t run, we check for immobilizer-related symptoms and confirm the key chip is the correct type before programming.
On a TSX sedan, lock/unlock working doesn’t mean the transponder is enrolled; the remote and immobilizer functions are separate layers.
The TSX sedan is typically turn-key; if you’re seeing start-detection issues, it may involve an aftermarket system or a swapped ignition setup that needs diagnosis.
Aftermarket and used TSX sedan keys/fobs can look correct but fail on FCC ID/chip type; we check compatibility before attempting to pair.
If you can’t provide ID and proof of ownership, we cannot cut, program, or provide guidance intended to defeat anti-theft protections.
For TSX sedan service in the USA and Canada, we start by confirming vehicle details and completing authorization checks (ID + proof of ownership).
We determine the TSX sedan key system and confirm chip/FCC compatibility before cutting or programming, especially for customer-supplied parts.
We cut the TSX sedan key blade when required, then enroll the transponder to the Honda/Acura immobilizer using the correct procedure for your year.
We verify that the TSX sedan starts and that lock/unlock and remote functions work (when present), then document the outcome before closeout.
| Stage | Deliverable | Format |
|---|---|---|
| Vehicle ID | Confirmed TSX sedan year/key style and service scenario | Technician notes |
| Authorization | ID + proof-of-ownership verification completed | Visual check (documented) |
| Cutting | Key blade cut to match TSX sedan locks (when applicable) | Physical key |
| Programming | Transponder enrolled and/or remote paired (when applicable) | Programming log summary |
| Verification | Start + lock/unlock + remote functions tested on-site | Functional checklist |
| Closeout | Final scope and price confirmed, then documented before leaving | Receipt + summary |
We explain what the TSX sedan needs (cutting, transponder enrollment, remote pairing) before beginning.
ID and proof of ownership are required in the USA and Canada before key work is started.
We confirm chip/FCC compatibility first, which reduces the odds of wasted time on mismatched parts.
We test the TSX sedan start and lock functions on-site and correct issues while we’re still there.
Most TSX sedan scenarios can be handled without towing, depending on access and vehicle condition.
Automotive key work is different from lockout-only service; we focus on cut + program + verify.
When compatible, we can work with OEM-style or select aftermarket parts to fit your TSX sedan scenario.
You receive a clear record of what was done: cut, enrolled, tested, and any limitations noted.
When you call, we route you to a mobile locksmith who can handle TSX sedan key work where supported.
A TSX sedan spare is usually simpler than an all-keys-lost situation because the vehicle can often accept an additional enrolled key.
The TSX sedan is typically turn-key; confirming your exact setup avoids ordering the wrong remote/key style.
Random “fits Acura” listings can be the wrong FCC ID or chip type. Compatibility checks reduce rework and delays.
Park the TSX sedan where the technician can work safely and reach the driver door and OBD port area.
Low vehicle voltage can interrupt programming. If the TSX sedan battery is weak, stabilize it before enrollment.
If you’re not locked out, scheduling helps control total cost and avoids last-minute constraints in the USA and Canada.
