Swift Caravan Door Lock Problems

Problem:

Owners of certain Swift Caravan models, particularly the ACE Firestar, have reported encountering stiff door locks. This issue does not stem from a jamming key tumbler, but rather from the friction caused by the interior plastic door lever. This problem has left many concerned about the possibility of their keys breaking in the lock due to the stiffness and clunkiness.

Causes:

1. Plastic Interior Lever Stiffness: The main issue lies with the interior plastic handle, which becomes incredibly hard to turn. This stiffness, in turn, affects the movement of the key. When the handle is moved manually, the key turns more smoothly.
2. Potential Door Misalignment: While some initially speculated that the door or frame could be out of shape or misaligned, further discussions clarified that the lock’s stiffness persists even when the door is open, indicating that alignment is not the root cause.
3. Lock Manufacturer: A common trend observed was that many who faced this issue had locks made by Hartal. These locks had parts made slightly out of spec, causing increased pressure and friction on the moving parts.

Solutions and Recommendations:

1. Proper Lubrication: While many initially turn to WD40 for its lubricating properties, it may not be the best solution. WD40 contains solvents which, although fine for metals, can react with certain plastics, making them stickier. Instead, caravan owners have found success with:
   • Silicone Lubricants: These are deemed safer for such applications and don’t lead to increased stiffness over time.
   • Graphite Grease: This has been suggested as a more effective lubricant that doesn’t wash out the grease present in the locks.
   • Graphite Powder: This is an alternative to grease that provides effective lubrication without causing further issues.
2. Lock Disassembly and Cleaning: For those with a Hartal lock, a popular solution involves:
   • Disassembly: Removing the cover with the Hartal logo provides access to two of the screws. The green and red covers must also be removed to reach the remaining screws. Once disassembled, owners can clean out any grime or obstructions.
   • Sanding: Some found success in using a bit of sandpaper to polish and smoothen the barrel bit of the lock.
   • Re-greasing: Before reassembling the lock, it’s essential to grease all the components adequately. This not only ensures smoother operations but also prolongs the lock’s life.
3. Regular Use: As with many mechanical devices, regular use can often ease stiffness. Some caravan owners noticed that the lock became looser and easier to operate as they used it more frequently.
4. Professional Assistance: If the problem persists or if owners are not comfortable disassembling the lock, seeking professional assistance or approaching the dealer might be the best course of action.

In conclusion, while the Swift Caravan’s door lock stiffness can be a concern, it’s reassuring to know there are several solutions available. Regular maintenance, proper lubrication, and periodic check-ups can ensure that your caravan’s door lock functions smoothly and efficiently.
