Overview & Operating Principle

▲

The LOCK ASSY HOOD is the bonnet latch assembly mounted on the front body cross-member or radiator support that secures the bonnet in its closed position during driving and releases it in a controlled two-stage sequence — primary release from the interior cable lever followed by secondary safety catch release at the bonnet leading edge — to allow engine bay access. The assembly integrates a spring-loaded latch fork that engages the bonnet striker pin when the bonnet is closed, capturing and retaining the striker under the spring's clamping load to hold the bonnet securely against aerodynamic lift forces at speed and against road vibration; a primary release pawl that is actuated by the interior release cable, which disengages the latch fork from the striker and allows the bonnet to rise to the secondary safety catch position — typically 50–80 mm above the closed position — rather than flying fully open in one motion; and a secondary safety catch lever accessible from the bonnet leading edge gap that the driver manually releases by feel to allow the bonnet to open completely. The two-stage release mechanism is a safety-critical feature — a bonnet that opens fully from a single cable pull without a secondary catch could open at speed from a cable actuated accidentally or by vibration, blocking the driver's forward vision entirely. The latch assembly is mounted in the underbonnet environment and must withstand continuous exposure to engine heat, road spray, pressure washing, and road salt while maintaining consistent release force and retention strength throughout the vehicle's service life.

This unit — HYUNDAI/KIA 81130D4010 — is manufactured to OEM-equivalent specifications: latch fork engagement depth and striker pin diameter tolerance, primary pawl spring load and release cable attachment geometry, secondary safety catch lever geometry and actuation force, mounting bolt pattern for body cross-member attachment, and overall assembly corrosion protection treatment are matched to the original part. Supplied as a complete assembly ready for installation. Available wholesale from 7.03 USD, MOQ 100 pcs, production lead time 33 days.

Bonnet latch assemblies fail through latch fork spring fatigue that reduces the clamping force on the striker pin — a spring that has weakened allows the bonnet to vibrate audibly at speed or to pop open on road impacts; through corrosion of the latch mechanism's internal components from road salt and moisture ingress that binds the pawl and prevents smooth release requiring excessive cable pull force; through cable attachment point wear that prevents the cable from transmitting its full travel to the primary release pawl; and through secondary safety catch corrosion seizure that requires a screwdriver or excessive finger force to release — a seized secondary catch is a safety issue that discourages drivers from releasing the catch correctly and increases the risk of an improperly secured bonnet.

Symptoms & Diagnostics

▲

Bonnet vibrating or producing a metallic rattling noise at motorway speed — the bonnet appears correctly closed at rest but vibrates audibly above 80 km/h — the latch fork spring has fatigued and can no longer clamp the striker pin with sufficient force to resist aerodynamic lift and vibration at speed; the bonnet is technically latched but insufficiently secured; confirm by pressing firmly on the bonnet leading edge with both hands — if the bonnet sinks noticeably under hand pressure and the rattle reduces, the spring retention force is insufficient.

Interior release lever requires significantly more force than previously — the cable moves but the bonnet does not release on the first pull — the primary release pawl is corroded or the latch mechanism has accumulated dirt that is binding the pawl; the increased cable force may eventually stretch the cable or fracture the interior handle if the latch is not serviced; lubrication of the mechanism with penetrating spray may temporarily restore correct release force but replacement is the definitive repair for a corroded latch.

Secondary safety catch that requires a screwdriver or tool to release — finger access to the catch lever is insufficient to overcome its resistance — the secondary catch has corroded to the point where its operating force exceeds the designed finger-release threshold; a catch requiring a tool to release is a safety deficiency — in an emergency or fire situation the driver cannot open the bonnet quickly; replace immediately.

Bonnet that does not latch when closed — the bonnet requires firm pressure or repeated slamming before the latch engages the striker — the latch fork is corroded in the partially open position and cannot rotate freely to capture the striker; or the striker height has shifted from a collision or incorrect adjustment, preventing the striker from reaching the latch fork's capture zone; confirm whether the striker is correctly aligned before replacing the latch.

Bonnet that releases from the primary cable pull but the secondary catch does not hold it at the safety position — the bonnet flies fully open from a single cable operation — the secondary safety catch has failed; a bonnet without a functional secondary catch is a serious safety hazard that must not be driven; the secondary catch failure may not be obvious until the cable is pulled, making this fault particularly dangerous.

Interior bonnet release handle that operates but produces no movement at the latch — the cable has detached from the primary release pawl at the latch end — the cable end fitting clip has fractured from the pawl attachment point; the handle moves freely with no resistance and no latch release; access to the latch for replacement requires reaching through the grille opening to manually release the latch before the bonnet can be opened.

Installation Tips

▲

If the bonnet latch has failed with the bonnet closed, gain access to the latch before ordering the replacement — reach through the front grille aperture with a long hook, stiff wire, or screwdriver to manually actuate the primary release pawl lever on the back of the latch body; on most designs the primary pawl lever is reachable through the grille centre; a second person applying gentle upward pressure to the bonnet leading edge while the pawl is manually released prevents the latch from re-engaging; confirm the bonnet can be opened before the new latch is available.
Transfer the release cable to the new latch before installation — the cable end fitting must engage the new latch's primary pawl attachment point fully; press the end clip onto the pawl ball pin until an audible click is confirmed and tug the cable to verify retention; a cable clip that appears engaged but has not seated will detach on the first interior release pull, reproducing the original failure immediately.
Apply a light film of lithium grease to all moving surfaces of the new latch mechanism — the latch fork pivot, primary pawl pivot, secondary catch lever pivot, and the striker contact face of the latch fork all require a thin grease film to prevent the corrosion that caused the original latch failure; apply grease sparingly — excess grease on the latch fork's striker contact face reduces the friction that contributes to striker retention under aerodynamic load.
Adjust the striker pin height to achieve the correct bonnet closing effort and latch engagement depth — the striker bolt is typically adjustable vertically and laterally through slotted mounting holes; the bonnet should close with a firm single-hand press and the latch should engage with a clear click; if the bonnet requires a slam, lower the striker; if the bonnet gaps are incorrect after latch installation, adjust the striker laterally to centre the bonnet in the aperture before final tightening.
Test the complete two-stage release sequence before closing the bonnet for the final time — with the bonnet propped open, pull the interior release cable and confirm the primary pawl releases smoothly with the designed force; manually close the latch to the secondary safety catch position and confirm the catch engages and holds the latch in the safety position; then manually release the secondary catch and confirm it releases with finger pressure only; only proceed to install the bonnet if all three functions are confirmed.
Install the new LOCK ASSY HOOD (HYUNDAI/KIA 81130D4010), close the bonnet, confirm it latches cleanly with a single firm press, confirm it does not vibrate or rattle at motorway speed, and perform five complete open-and-close cycles confirming smooth primary cable release and correct secondary catch operation before returning the vehicle to service.

Tools: long hook or stiff wire for emergency latch access, screwdriver for striker adjustment, lithium grease for mechanism lubrication, torque wrench for latch mounting bolts.

Frequently Asked Questions

▲

How can the bonnet be opened when the release cable has broken or detached at the latch end?

Emergency bonnet access when the cable is broken or detached from the latch requires manually actuating the primary release pawl through the front grille structure. On most vehicles a long screwdriver, hook, or stiff wire inserted through the grille centre can reach the latch body's release lever from the front; on some designs the latch is accessible from below through the front bumper lower aperture. A second person applying gentle upward hand pressure to the bonnet leading edge while the pawl is manually actuated prevents the latch from re-engaging after each attempt. Never force the bonnet by levering from the front — this bends the bonnet leading edge and body cross-member. ok.parts supplies bonnet latch assemblies at wholesale MOQ from 7.03 USD per unit.

Is it safe to drive with a bonnet that latches but vibrates at motorway speed?

A bonnet that vibrates at motorway speed from a fatigued latch spring must not be driven at speed until the latch is replaced. The vibration confirms that aerodynamic lift forces at speed are overcoming the weakened spring's clamping load on the striker — the bonnet is retained but by a progressively reducing margin. A bonnet that opens at motorway speed blocks the driver's entire forward vision instantly, creating a collision risk with zero reaction time. The vibration is the warning that the spring has already partially failed; continued driving at speed risks complete spring failure and bonnet opening. The vehicle should be driven only at low speeds — urban use only — until the latch is replaced.

Frequently Replaced Together

▲

Part	Reason for Combined Replacement
Bonnet Release Cable Interior handle to latch body — application-specific	The bonnet release cable transmits the interior handle pull to the primary latch pawl and is subject to the same corrosion and fatigue conditions as the latch body. A cable that has been operating against a stiff corroded latch has accumulated inner wire strand fatigue from the repeated high-force pulls required to release the binding mechanism. If the latch has failed from corrosion binding, inspect the cable for increased stiffness and replace it simultaneously if the inner wire feels noticeably stiffer than a new cable — a fatigued cable will fracture within a short interval after the new latch restores the normal release force.
Bonnet Striker Body-mounted striker pin — application-specific	The bonnet striker is subject to the same underbonnet corrosion environment as the latch body and develops a wear groove from repeated latch fork engagement over high mileage. A grooved striker reduces the latch fork's effective engagement depth on the new latch, potentially allowing the bonnet to vibrate at speed despite the new latch's correct spring load. Inspect the striker surface for grooves and corrosion and replace if wear is visible to ensure the new latch operates against a correctly profiled striker.
Bonnet Hinge Set Left and right hinges — OEM ref. varies	A bonnet that does not align correctly in the aperture after latch replacement — gaps uneven or bonnet standing proud on one side — may have a worn or bent hinge rather than an incorrectly adjusted striker. Inspect both hinges for pivot wear and corrosion that would allow the bonnet to sag or shift laterally from the designed position; a bonnet that cannot be centred in its aperture by striker adjustment alone requires hinge inspection and replacement before the aperture alignment can be correctly set.
