Where is the release catch situated on a 54 plate hyandai coupe ?

I had this problem vauxhall garage had to drill a hole in the radiator grille and use a special tool to pull the bonnet catch lever.(apparently its a common fault)
only way as there is no way of getting at the cable or the catch from under the car (only way is to remove the radiator and the bolts for that are guess what at the top under the bonnet).

get somone to push down on the bonnet and pull it up while u pull the relise handle. if dont work then strip the front grill and u should be able to open the catch manualy

You don't specify whether its just that you can't find the release catch, or whether the release catch is stuck / broken,

In the UK (Right hand drive car) the release catch is situated in the left (passenger side) footwell, within about a foot of the lower front door hinge. In a Left Hand Drive car, I guess this would be reversed (i.e. right hand side footwell). Pull, and it semi releases the hood. Next, walk to the front of the car, pull the hood up about 1" and insert your fingers about a foot left of center. Sweep to the right, and you'll release the secondary catch and the hood will be open.

However, if its stuck / broken, then ......

You need to work underneath the front of the vehicle - the idea is to get at the catch and release it with a long screwdriver flicking the catch to open the bonnet -or getting a grip of the cable if it is hanging loose ( i.e. broken ) then getting a grip of the cable with mole grips or even pliers - to pull and release the cable / bonnet.

Once the bonnet is open - you can deal with renewing the cable assembly, or greasing it thoroughly.

find bonnet catch and while someone pushes down on bonnet, pull the cable from behind the release lever (normally a black plastic covered wire) either the cable has siezed or the outer cable has sliped out of its retaining plate, if cable has broke, then access from under car with long rod to push lever over, again someone lightly pushing on bonnet will make it eaiser

Have someone lift on the bonnet while you pull the release handle.

Get a second person to pull bonnet catch and you push up and down on the bonnet whilst catch is being pulled. 1, cable possibly stretched, 2, look at bonnet catch under the coloum to see if wire is attached, 3, try and lie under car and look up the back of the bulkhead to see the catch and release it manually. Hope that helps.

Flip up the badge on the front radiator grille, put key in and turn one way to release first catch, then turn other direction to open.

TL

There are two release catches about 15" to the right and left of the centre safety catch. Roughly at each end of the top of the radiator.

The bonnet release cable goes first to the right hand one then there is a wire from that to the left, in a daisy chain way. They are typically French, cables fit into plastic levers ( a bit like bike brakes) not metal which break easily. replacements are not cheap. You need to be able to pull the cable to both catches to get the bonnet up. I managed to do this from underneath. In my case the, left hand one was broken and right hand one was working, but the getting it open broke the bit that that pulls the left. Managed to away with buying just one new catch as they are identical, swopping the right partly broken one over to the left side.
