To guarantee smooth functionality, it's crucial to ensure that the interior half of the latch is correctly installed with the handle in the locked position. Improper installation might prevent the latch "tooth" from engaging with the locking mechanism, causing the inside door handle to become stuck. Refer to your owner's manual for step-by-step instructions on correct installation.
Additionally, be mindful of your door thickness, ensuring it aligns with the FIT GUIDE requirements. This attention to detail will contribute to the seamless performance of your door latch.
