Replacement service for multi-point entry door lock bodies

Description

We offer comprehensive replacement and linkage calibration services for residential entry doors equipped with multi-point locking systems. As these systems involve upper and lower transmission rods and lateral locking points, precise alignment during replacement is crucial to ensure smooth latch movement and proper handle operation. Our service includes replacing the lock assembly, lubricating transmission rods, and fine-tuning locking point positions.
After an order is placed, we remotely gather details regarding the door brand, original lock model, and specific issues to source a fully compatible replacement assembly. On-site work begins with removing the faceplate and marking connection points, followed by installing and securing the new lock body, connecting the transmission rods, and adjusting the travel clearance.
Upon completion, we conduct repeated opening and closing tests, checking handle operation (both inside and out), key turning resistance, and locking point extension. We also inspect the strike plates on the door frame for wear, making adjustments or replacements as necessary. Finally, we provide operating instructions for the new lock and advise on simple methods for checking the smooth operation of the transmission rods.
