use a qualified locksmith to get the job done properly
£60 - 100 is a good price then if it retro fits , cool. If cuttting out, adjusting keeps and alignments need to be done and the jobs done well. Its well worth paying a MLA Locksmith to do it!!
you can get into a hell of a bother if its not done right. Does this affect your insurance, a lock not being fitted right?? Mmmm
