P2000 lock gearbox and lock case units provide the critical mechanism inside multipoint and single-point lock systems for patio doors and select window types. When the internal gears or latches fail, replacing the gearbox restores full locking function, ensuring smooth handle movement and dependable security in homes and commercial buildings. AmesburyTruth P2000 gearboxes are engineered for precise fitment in doors originally equipped with these systems, helping extend door lifespan and maintain property safety.

Comprehensive Replacement Options

This collection covers both active and passive P2000 gearboxes, as well as dedicated lock cases for 35mm, 45mm, and 60mm backset depths. You'll find models for both American and Euro cylinder types, with or without faceplates, designed for direct swap-in replacement. Related P3000 lock case options address spring latch and deadbolt needs for wider compatibility.

Use Cases and Compatibility

P2000 lock gearbox replacements are ideal for fixing doors where the key or thumb turn no longer operates the deadbolt or latch, or when the handle feels loose, stiff, or inoperable. These parts are especially common on hinged patio doors and some commercial swing doors using AmesburyTruth multipoint or single-point locking hardware. Compatible systems often include the Premier and P2000 door series from AmesburyTruth; always check your backset (35mm/1-3/8 inch, 45mm/1-3/4 inch, or 60mm/2-3/8 inch) and cylinder format to ensure a match. For specific applications, select options like the 45mm American cylinder gearbox or the 35mm replacement lock case for a direct fit.

Installation and Replacement Tips

  • Always confirm the backset size and cylinder type before ordering; most units specify American or Euro cylinder compatibility.
  • These gearboxes are designed for straightforward installation with common hand tools, such as a T-20 torx driver for mounting screws.
  • Reversing the latch or changing handing may be required,extend the deadbolt, pull the spring latch, and rotate as needed before reassembly.
  • For multipoint locks, replace only the failed gearbox, not the entire lock strip, to minimize labor and cost.

Frequently Asked Questions

  • Are these gearboxes compatible with all AmesburyTruth doors?
    These lock gearboxes are designed for use with P2000 and P3000 systems, primarily on patio doors and select commercial doors. Confirm your door's original hardware or consult the product documentation for compatibility.
  • Can I replace just the gearbox, or do I need the full lock strip?
    You can often replace just the failed gearbox. This saves cost and effort compared to changing the entire multipoint locking assembly.
  • How do I know if I need a passive or active gearbox?
    Active gearboxes operate the main latch and deadbolt, while passive models are for secondary doors without keyed access. Check your door's locking function to determine the correct type.
  • Where can I find more specifications?
    Each product page, such as the options for the 60mm passive lock case or 60mm active gearbox, provides detailed measurements and compatibility information.
