For turning a VW engine by hand, the UTMALL T40058 socket is the relevant choice for specified Audi/VW engine work, while the EMPI Woodruff key fits certain air-cooled VW crank pulleys. These are not ignition keys. For starting or locking a vehicle, compare the ignition-lock cylinders by part number and vehicle fitment instead. The options below cover those different needs, so confirm whether you need to rotate an engine, secure a crank pulley, or replace an ignition component before ordering.
| Product | Best For | Key Check |
|---|---|---|
| UTMALL T40058 Turning Socket | Turning a crank pulley during service | Tool application and engine fit |
| EMPI Crank Pulley Woodruff Key | Air-cooled VW crank pulley | Engine family and part number |
| 1K0905851B Ignition Lock Cylinder | Selected newer VW models | OE number and model year |
| X AUTOHAUX Steering Lock Cylinder | Selected VW and related models | Full vehicle and OE-number match |
| DASPARTS Ignition Lock Cylinder | Listed older VW applications | Confirm vehicle-specific fitment |
UTMALL T40058 Crankshaft Turning Socket
This is the closest match for someone searching for a tool to turn an engine assembly by rotating a crank pulley. The listing describes it as a special turning socket for VW and Audi applications, including Audi A6 and A8 examples and an A6 C7 2012. It also describes steel construction intended to resist wear.
Best for: A mechanic or vehicle owner who needs the specified T40058-style tool for crank-pulley rotation. It was selected because it directly addresses engine turning, unlike an ignition key or lock cylinder.
Limitation: The feature list names particular Audi examples rather than a comprehensive VW engine fitment list. Verify the tool number and service application before purchase.
EMPI Air-Cooled VW Crank Pulley Key
This Woodruff key is a small crank-pulley component, not a wrench or ignition key. The listing identifies it for 1200–1600cc air-cooled applications and gives part number 113-105-249. Named vehicles include Type 1 Beetle models from 1961–1979, Karmann Ghia from 1961–1974, Type 2 from 1961–1971, and Type 3 from 1964–1973.
Best for: Owners restoring or servicing one of the listed air-cooled VW engine families who need the crank pulley key itself. The stated engine range and part number make it easier to compare with an existing component.
Limitation: It is not presented as a universal VW part. Avoid choosing it for later water-cooled engines or an unlisted application without confirming the required part number.
1K0905851B Ignition Lock Cylinder With Key
This product is for vehicle ignition and steering-lock replacement, not for manually turning an engine during repair. It lists reference numbers 1K0905851B, ILA920, and 1131nc12919, and fitment for selected VW Golf, Jetta, Tiguan, EOS, and Rabbit models from 2004–2018. Audi Q3 models from 2015–2018 are also named.
Best for: A buyer whose original lock-cylinder part number and vehicle application match the listing. It was selected as a direct comparison for newer VW ignition-lock needs.
Limitation: The listing notes that the remote-key shell needs a separate battery installation for full functionality. Confirm the exact part number and year because listed model ranges alone do not establish fit.
X AUTOHAUX VW Steering Lock Cylinder
This cylinder is listed for starting the vehicle, operating accessories, switching off the engine, and locking the steering wheel. Its OE references include 1K0905851B and several related numbers. The stated applications include selected Jetta, Golf, EOS, Tiguan, Rabbit, Scirocco, Touran, and Caddy models, plus listed Audi, SEAT, and Škoda vehicles.
Best for: Buyers who need a steering-lock ignition component and can match both the vehicle details and an OE reference number. The broad list makes it useful to compare against a specific repair requirement.
Limitation: Fitment spans many models and years, so do not rely on a model name alone. The listing specifically advises confirming make, model, year, and OE number.
DASPARTS Ignition Lock Cylinder With Keys
DASPARTS lists this ignition lock cylinder with keys under part numbers 113905855B and 113905855, as well as reference 4119058551. The description says it is for VW 1971 and later models, but it does not provide a detailed vehicle-by-vehicle fitment chart in the supplied product information.
Best for: Owners of an older VW who have verified that one of the listed part numbers matches the part they need. It provides a separate option from the newer 1K0905851B-style cylinder.
Limitation: “1971 and later” is broad, and the supplied details do not identify every compatible model. Confirm fitment with the vehicle and original part before ordering.
Buying Guide
Do you need to turn the engine or replace an ignition key?
These are different jobs. A crankshaft turning socket is a service tool used to rotate an engine assembly through the specified pulley arrangement. A Woodruff key is a small mechanical part used at a crank pulley. An ignition cylinder or key operates the vehicle’s starting and steering-lock system. Match the product category to the repair before comparing brands.
How should you check fitment?
Use the vehicle’s year, make, model, engine family, and the number on the existing part. Compare the complete OE reference, not just a similar-looking number. For engine tools, verify the tool designation and the service procedure for the specific engine. For replacement cylinders, check the vehicle list and whether the product includes keys or a remote shell.
What matters for air-cooled VW pulley work?
Check displacement, engine family, vehicle generation, and part number. The EMPI listing specifies 1200–1600cc air-cooled engines and names several classic VW models. That is more useful than assuming a part labeled “VW” fits every engine.
When should you ask a professional?
Get qualified help if you cannot confirm the correct engine-turning point, ignition-cylinder fit, or key programming needs. Incorrect tool use or an incompatible ignition part can interrupt a repair or prevent normal vehicle operation.
Frequently Asked Questions
Is a crank pulley key the same as an ignition key?
No. A crank pulley key is a mechanical engine component. An ignition key operates the vehicle’s ignition and lock system.
Which product is intended to turn a VW engine?
The UTMALL T40058 is the listed turning socket. Confirm its application for the specific engine before use.
Does the EMPI key fit every VW engine?
No. Its listed application is for specified 1200–1600cc air-cooled VW engines and named vehicle ranges.
Can I choose an ignition cylinder by model name alone?
No. Compare the vehicle year and the original OE part number because fitment can vary within a model line.
Does the 1K0905851B product include a fully ready remote?
The listing says the remote shell requires separate battery installation for full functionality. Read the product details and verify what is included.
