4K0 - Central-locking system with remote and interior operation
L0L - Left Hand Drive version
Diagram ref no 12
These modules control central locking functions, interior locking switches, key fob response, and vehicle security features. When they start to fail, owners experience everything from random locking behaviour to doors that refuse to open at all.
This replacement module offers dependable performance and restores proper locking functionality without relying on original manufacturer terminology. Designed to match the dimensions and electrical behaviour of the original component, it ensures smooth installation and reliable operation—ideal for aging Cayenne models where lock failures have become increasingly common.
What Door Lock Modules Do
Door lock modules are responsible for regulating several vehicle functions:
Primary Functions
- Locking
and unlocking doors electronically
- Actuating the central locking system
- Processing key fob and interior switch signals
- Engaging the deadlock/anti-theft mechanism
- Ensuring doors latch securely while driving
- Supporting comfort access features (if equipped)
Without a functioning lock module, the door may not latch, may unlock unexpectedly, or may stay permanently locked.
Why Door Lock Modules Fail
Over time, the Porsche Cayenne (especially early 955/957 models) is known to suffer from lock actuator issues due to wear, aging electronics and environmental exposure.
Common Failure Causes
- Internal
motor wear from repeated locking cycles
- Moisture
intrusion leading to corrosion
- Electrical
circuit degradation with age
- Temperature
fluctuations weakening internal components
- Broken
micro-switches used for door position sensing
- Gear
wear inside the actuator mechanism
- Faulty connector pins causing intermittent operation
Symptoms include:
- Door won’t lock or unlock
- Random self-locking
- Key fob intermittent response
- Door cannot be opened from inside or outside
- Alarm triggers unexpectedly
These issues are extremely common on older Cayenne models, often requiring a full lock module replacement.
