Can't open bonnet of ford focus key turns one way to the left and releases the catch but won't turn to the right to open the bonnet.

Try pulling up on the hood while the lock is operated.

Open or get through the hind seats. If this does not work, you may have to bring your car to someone who can jim out the latch for you. The latch has to be adjusted.

either under the steering wheel or the key goes in the front behind the ford badge where you turn to left to open and the right to release the safety catch

Go to the ford badge at the front of the car
Swivel the badge (its spring loaded)
Insert your ignition key and turn to the left (position 1)
The bonnet should pop up
Turn the key to the right (position 2)
You can now lift the bonnet.

push the key right in and turn to the left untill it click open then turn to the right to open. if the key still doesnt turn try some lubracation eg wd40 spray.

pig of a job but you will need to get a long screwdriver up from underneath and release the second click (safety release)

On my 05 model, you need to twist the ford badge on the bonnet anti-clockwise, pushing the left side of the badge down, which will reveal a keyhole. This is then opened with your ignition key. Once the bonnet pops, you just need to release the bonnet catch.
Hope this 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.

Stuck lock, bonnet won’t open ,,,
You do not need to drill holes in the grill or pay ford £200+
DIY..How?
Look into the grill at the top you will find the bottom of 6 plastic revscrews, 4 you get two via the grill slots use a chisel and cut them off, Then one either end of the grill. Place the chisel between two plastic layers, gently lift , check and cut, one each end.
With a wiggle that’s the top loose, There are two clips holding the bottom in place Put your fingers through the bottom slot in the grill, push down clip and greatly pull the grill, do both sides, It won’t come right out but your aim to loosen it., The lock is held in place in a sleeve with a plastic clips each side, you have push the barrel with a suitable item, this is to push it out of the sleeve and out of its housing, It may need a tap!!
Gently wiggle and pull the grill off

Lock
The lock is a ‘lock barrel along a shaft to a white plastic coupling’ this fits in to the ‘bonnet lock’
The security is at the coupling to bonnet lock in the form of a cross shaped plastic key
The key is fitted and held in place in the coupling, and when installed it’s fitted in to the lock, and once it’s in the lock part it will not come out, so therefore any jolt, pull, movement dislodges the plastic key from the coupling side and due to its design it will not slot back in so the lock barrel just rotates
To open you have to apply pressure on the shaft towards the left and into the coupling and turn the key in the lock barrel at the same time in a aim to get the coupling to catch the plastic key (take a few minutes) but it opens in the end if this is the fault, (alternatively remove the two bolts that hold the bonnet catch to the bonnet)
Once bonnet open remove the bonnet lock mechanism, then with draw the lock barrel, shaft, coupling, By looking in side you will understand regarding the cross key
Anyway you need to remove one of the catches from the side of the plastic key This way it will fit back in to coupling.
Reassemble
This is a brief description But the cost to me was 45 minutes, £2 for a pack of plastic rivets / screws, and I cached my bumper with the chisel £5 for a touch up stick Total £7. Well worth the time and effort
