Westfalia Keys by Code
What code series does Westfalia use and which category does each cover?
Westfalia uses three distinct code systems. The 2W-series (2W01–2W50) and W-series (W01–W50) cover AHK and AHV detachable swan-neck coupling locks — used on towbars across all major European vehicle brands. The 5-digit numeric range (20001–50000) covers towbars manufactured after 2008 where the code is stamped directly on the lock cylinder. Bike carrier keys use the last 2 digits of the 3 lock numbers (001–020) to identify the correct key
Where is the Westfalia key code on different applications?
On 2W-series towbar systems the code is on the original key shaft (e.g. 2W22) or derivable from the lock barrel — take the last 2 digits of the 5-digit number and prefix with 2W. On 20001–50000 series towbars the full 5-digit code is stamped directly on the lock cylinder and entered as-is. On Westfalia bike carriers the code is the last 2 digits of the number stamped on each of the 3 lock points. A 3-digit number on the lock body is a batch number — not a key code.
My Westfalia towbar lock shows a 3-digit number — can I still order a replacement key?
No. A 3-digit number on the Westfalia lock body is a batch number — not the key code. It cannot be used to cut a replacement. To order, you need either the 2W-series code from the original key shaft, or the full 5-digit code from the lock cylinder if the towbar was manufactured after 2008. If no original key remains and the lock shows only a 3-digit number, the only option is a master key set or lock cylinder replacement.
How do I derive the 2W key code from the 5-digit number on my Westfalia lock?
Take the last 2 digits of the 5-digit number on the lock cylinder and prefix them with 2W. For example, if the lock shows 33322 the key code is 2W22. If the lock shows 48507 the key code is 2W07. This method applies to all Westfalia detachable towbars manufactured after 2008. For towbars manufactured before 2008, the code appears directly on the original key shaft as a W-series or 2W-series code.
Can a Westfalia towbar key from the 2W-series operate a lock showing a 5-digit code?
Yes — if the last 2 digits of the 5-digit code match the 2W-series key number. The 5-digit lock number and the 2W key code are two representations of the same lock configuration. A lock showing 33344 uses key 2W44 — both refer to the same cylinder. Pre-2008 Westfalia towbars manufactured with a 3-digit code on the lock cannot be matched to the 2W-series without the original key — the 3-digit number is a batch reference, not a cylinder code.
