Installation Notes and Tips

Verify vehicle fitment by year, make, model, and door configuration before installation. This part is listed for door mounting locations and includes applications with front and sliding door notes on select vans and utility models. Compare the existing lock core, keyway, and finish to confirm the correct replacement before disassembly.

For best results, inspect the door latch, linkage, and surrounding hardware during service so the new lock operates correctly after installation. DL-7B is also a practical choice for restoring matching door locks on Chevrolet Impala, Oldsmobile Cutlass Supreme, and Pontiac Bonneville applications where the original lock has failed.
