Bonnet release broken

This will depend on where the break is. If it is broken nearest the lever inside the car you could grab the cable with a pair of grips and pull it that way.
Do you need to open the bonnet to get the vehicle started? If the car runs and drives normally take it to a Good mechanic and they will have the tools to get it open.
If the cable has broken nearer the bonnet release at the front of the car it will be a lot more work.
If you use a torch and look behind the badge on the front grille you might be able to use a long flat head screwdriver to hook the release lever to 'pop' the bonnet but some car manufacturers fit a metal plate behind the grille to stop you doing this.
You could try SAFELY raising the front of the car and see if you can get to it from underneath.
Your LAST and more expensive method would be to damage the front grille and get to it that way.

try coming up in front of the radiator with a long lever and release the bonnet latch
when you have the bonnet up then adjust the cable and tighten up the cable clamp

you will have to come up in front of the radiator with a long lever and push the latch lever sideways . Use a friend to push down on the bonnet as you push the lever as it will release the pressure on the latch and make it easier to move.

Under the dash on the driver's side is a bonnet release. Pull the release towards the seat. This should release the first bonnet restraint.
Next, under the front of the bonnet is a secondary release lever. Slide this lever to the right and lift the bonnet.
On the right side of the engine compartment on top should be a prop rod for the bonnet. Put this into the receptacle hole on the bonnet.

If the inside latch won't work, you'll have to reach up from underneath the hood to pull the lever over to open. Usually a flatblade screwdriver will help. The latch lever has to move towards driver's side to open.

easiest way could b to peel away layers of interior panels or where cable pops out an follow cable to where u can get some pliers on the broken piece, may have to peel back insulation on cable to access broken wire to pull on with pliers .hope this can help, good luck

If the cable is not broken,get a friend to push/lift bonnet while you pull release,this should release bonnet.

Try pushing down on the hood while someone else pulls the lever to open the hood. Then lift up and release latch as usual.
Could be broken spring in latch.

Hello There

In short no there isn't, however it's most likely your plastic release lever is broken and not the metal cable, you need to open the cover over the release lever, there will be a cable you can pull using a gripper and it will release the bonnet, you can easily replace the plastic llever and it's reletively cheap.

Hope this helps, please don't forget to rate me.
