What This Product Does
This lower mechanism engages the bonnet's upper locking component as the lid closes. Its mounting on the body provides the fixed catch needed for bonnet retention and normal release operation. Correct engagement depends on the condition and alignment of both locking components.
Functions
- Receives the matching upper bonnet lock.
- Holds the bonnet shut through mechanical engagement.
- Forms part of the bonnet closure and release system.
Technical Details
- Porsche genuine component, reference 99751105301.
- Location: Front; lower portion of the bonnet lock.
- Each supplied assembly diagram specifies one lower lock.
- 997.2 diagram coverage: Carrera 2009–12 and Turbo / GT2 RS 2010–13.
- 987 diagram coverage: 987C.1 Cayman 2006–08, 987.2 Boxster / Boxster S 2009–12 and 987C.2 Cayman 2009–12.
- The upper lock, micro switch and mounting hardware have separate entries in the diagrams.
Symptoms of Fault
- Inconsistent engagement when closing the bonnet.
- Sticking or irregular operation during release.
- A closed bonnet that moves or rattles.
- Visible corrosion, wear or damage around the catch.
- Poor engagement after damage to the lock or surrounding bodywork.
Why Replacement Matters
A damaged or deteriorated lower mechanism can prevent the upper and lower components from engaging correctly. Replacement addresses a confirmed lock fault and may be necessary during front-end body repairs. Check the upper catch, release components, micro switch and fasteners at the same time; alignment or cable faults should not be mistaken for failure of the lower lock.
FAQs
Which bonnet does this lock serve?
It is intended for the front bonnet, not a rear lid.
Is this a complete locking kit?
The identified product is the lower lock. Separate diagram entries cover the upper mechanism, micro switch and associated hardware; do not assume these are included.
How can I check suitability?
Use reference 99751105301 alongside the detailed applications above, and verify the vehicle identification number where necessary.

Application: Replacement of failed, worn, corroded or misaligned hood/boot latch; essential when restoring exterior hardware or after accident repairs; recommended when the latch shows play or fails to keep bonnet secure.
This latch provides a secure locking point to keep the front hood firmly closed, preventing accidental opening while driving. It ensures the bonnet sits correctly when shut, maintaining proper body alignment and sealing. The latch is engineered for strength and durability, withstanding repeated use and environmental exposure. By replacing a worn, corroded, or faulty original latch, it restores factory-level safety, reliability, and proper hood operation.
