Jaguar X-Type X400 Door Lock Barrel Cylinder Mechanism Right O/S 1X43-F21990-AC

Jaguar X-Type X400 Door Lock Barrel Cylinder Mechanism is an original component from the Internal locks and latches group, designed for precise integration with the factory body locking system. It ensures the correct operation of the lock on the driver or passenger side (depending on the RHD/LHD version), guaranteeing secure locking and unlocking of the door while maintaining factory safety standards.

Purpose and function in the locking system

The presented mechanism is responsible for transferring the key movement to the internal door locking system on the right side of the vehicle. In practice, this means:

• mechanical control of the door latch using the key,
• cooperation with internal lock rods and levers,
• stable maintenance of the closed or open position of the door leaf. Thanks to a design consistent with Jaguar factory standards, the cylinder maintains the correct operating geometry, which reduces the risk of the lock jamming and improves the comfort of daily vehicle use.

Construction and fitment for Jaguar X-Type X400

The mechanism has been designed specifically for the X-Type X400 platform, taking into account the door architecture and rod routing characteristic of this model. Proper positioning on the right side of the vehicle allows for:

• proper fitment with the door panel and internal lining,
• correct connection with the factory door lock,
• maintaining the original position of the cylinder relative to the seals and handle. As an element from the Internal locks and latches group, the mechanism contributes to the complete door security system, influencing the convenience of use and the system's resistance to operational wear.

Condition, origin, and benefits of using a used part

The offered mechanism comes from a Jaguar vehicle and is a used part, which in practice means maintaining the original specification while reducing repair costs. Using an OEM part from disassembly allows you to:

• maintain factory fitment to the door and lock,
• preserve compatibility with the original key and locking system (after proper installation and configuration),
• minimize the risk of installation problems typical of replacements with different geometry. For workshops and individual users, this means a practical, technically sound solution for repairing the door locking system in a Jaguar X-Type X400.

Installation tips and service application

The right-side door lock cylinder mechanism is best installed in a workshop environment, following procedures for door trim removal, rod routing, and latch operation checks. After installation, it is recommended to:

• check the smoothness of the key rotation throughout the full range,
• verify correct locking and unlocking in various door positions,
• check the cooperation with the central locking system (if present in the vehicle). This approach helps to reduce the risk of having to disassemble the door again and ensures stable operation of the system in the long term. If you are planning a comprehensive repair or upgrade of the door lock area in your Jaguar and need other elements from the same group, such as cylinders, latches, or locking mechanisms, check the available parts in the Jaguar internal locks and latches category.
