Hi everyone , newbie here . If anyone is interested I'm suffering from the problem of my emergency key not working. I've looked on the forums here and there have been suggestions of using WD40 type lubricant but while in Lidl's I purchased an aerosol of " Graphite Oil " for £2.99p. It says on the can that it doesn't dry out and leave a gungy residue so I thought it would be preferable to lubricate the locks. Hope this is of use to others. Cheers H.
