Product Details

Standard Ignition US-804 is built for Nissan ignition lock cylinder and switch replacement where the original assembly is worn, damaged, or no longer operating correctly. This assembly is listed for 2000-2002 Nissan Maxima, 2002-2006 Nissan Sentra, and select Sentra models with keyless entry and immobilizer equipment. For 2001 and 2002 Nissan Maxima applications, service manual or scan-tool access may be required for anti-theft system repair and installation procedures. The US-804 part number is also referenced under cross numbers such as CS1164 and KS7164 for the same application.

Common Issues This Part Can Address

• Key will not turn or the ignition cylinder binds
• Ignition switch electrical contacts are intermittent or failed
• Vehicle starts inconsistently due to worn lock and switch components
• Security-system related replacement is needed after lock assembly wear or damage
• Original ignition assembly no longer matches the vehicle’s coded setup

Installation Notes

Verify the vehicle’s anti-theft and immobilizer requirements before installation. Some 2001-2002 Nissan Maxima applications require scan-tool security access, and certain Maxima repairs call for service manual procedures. This assembly mounts on the column and uses male and female connectors with blade terminals, so connector style and terminal count should be matched to the original unit before installation. Standard Ignition US-804 includes instructions and keys, along with the mounting bracket(s) needed for the assembly.
