Towbar keys are replacement mechanical keys used to lock and secure detachable towbar coupling lock systems and swan-neck towball locking mechanisms on cars, SUVs, and light commercial vehicles — for Westfalia, Bosal, Brink, Oris, Witter, GDW, TowTrust, and ACS detachable towbar systems. Each key is cut to the alphanumeric code stamped on the lock barrel face or original key shaft. No programming is required. No locksmith visit is needed after delivery. The code alone is sufficient to reproduce the correct blade profile — no original key is needed to place an order.
The code on the lock barrel face or original key shaft is entered into the drop menu — every key ships cut to that exact code and arrives ready to insert and use immediately.

What are towbar replacement keys and how do they work?
Replacement mechanical keys cut to a specific alphanumeric code that operates one detachable towbar lock cylinder. Each cylinder contains a unique internal pin configuration — only the blade profile matching that configuration releases the coupling mechanism. Used on detachable swan-neck towballs and AHK-type coupling lock systems across all major European towbar brands.
How are towbar replacement keys cut to code?
A precision milling machine shapes the key blade to the exact specifications of the code provided. The code identifies the unique blade profile matching the internal pins of that lock cylinder. No original key is needed for the cutting process. The replacement arrives ready to insert and use immediately after delivery.
Where is the key code on a towbar lock?
Stamped on the lock barrel face or original key shaft as a short alphanumeric sequence. On most detachable systems the code appears on the lock barrel face or engraved on the key shaft. A 3-digit number on the lock body is a batch number — not the key code. A readable alphanumeric code on the key shaft or barrel face is required to place an order.
Can I order a replacement towbar key without the original key?
Yes, if the alphanumeric code is readable on the lock barrel face. Locate the code, enter it into the drop menu, select the matching product. If only a 3-digit batch number is visible on the lock body and no original key is available, the code cannot be determined from the lock alone — the lock cylinder must be decoded by a locksmith.
Will a replacement towbar key fit my existing lock?
Yes, when cut to the exact code corresponding to that lock cylinder's internal pin configuration. Fit issues occur only when the wrong code is ordered or the cylinder is physically damaged. Verifying the exact alphanumeric code on the lock barrel face or key shaft before ordering eliminates fit issues entirely.
