Door lock barrel replacement

hi guys,just bought an other freelander (t reg)the other day for £150.it had a leak on the radiator which was replaced and all's good so far.only problem i have is that( apart from being petrol) is it only came with 1 key and fob.the lock barrel has been tampered with a screwdriver or something.does anyone know how easy is it to replace not that botherd if its a different key.any part numbers would be great,,cheers

Yes very easy to change, just remove the door card then undo the 2 bolts that hold on the exterior door handle, lift out the handle from outside the car and the lock barrel will come out with the handle, just be ready to catch it as it will drop out.

£150, bargain
