Product Information

This Winkhaus Thunderbolt Multipoint Door Lock Refurbishment Kit is designed to restore full functionality to damaged or worn locks featuring a split spindle centre case with a latch and deadbolt, plus two Thunderbolt locking modules. Compatible with uPVC, timber, aluminium, and composite doors, this compact and cost-effective repair solution allows professionals to replace only the essential components—without needing to install a full-length replacement lock mechanism.

Most multipoint locks fail due to issues with the internal gearbox, spindle follower, or bolt mechanisms, while the faceplate and rods are often still in usable condition. This kit provides all the bolt-on parts needed for a complete lock overhaul, making reuse of the existing faceplate and drive rods both practical and reliable.

Packaged in a compact box no larger than a pizza box, this kit is ideal for locksmiths and trade professionals looking to carry stock for same-day repairs. Avoid delays, eliminate long parcel handling, and complete the job in one visit by simply selecting the correct backset and configuration for your lock.

Key Benefits:

• Fast installation – no trimming or full-length replacements required
• Universal compatibility with uPVC, aluminium, timber, and composite doors
• Perfect for van stock – avoid return visits and long delivery waits
• Eco-friendly – reduced packaging waste and lower carbon emissions
• Simple one-visit repair – no need for exact lock model identification

This sustainable refurbishment solution significantly reduces parcel size, job-site waste, and emissions—making it the smart and eco-conscious choice for restoring Winkhaus Thunderbolt multipoint door locks.
