Dead locks

Hi all anyone know any info on putting dead locks in defender doors as the door locks are a pile of ****.... Neil

Just looking into myself, found a company in bolton that can fit but it is going to cost me about £300. There were some pictures in last months land rover mag under the article what can you buy for £25k, there was a picture showing the locks, that's what gave me the idea.
Not sure it's worth it but like you the locks are crap on my 90. Would be interested in what you do and how much.cheers nick
