But there lies the problem. If you cut a key of theirs, and they cock the ignition up then no matter of they forced it, you told them no guarantee they will be straight in gobbing off and threatening.
We had one in before after Timpsons cut a SAAB, and after trying it were stuck, ignition would not turn. They wanted us to write a report about the cutting of they key etc, to take it further with T's. We declined, obviously don't know the full story and don't want to be involve in anything like this.
I did a 2008 Mondeo remote key a few months back and the customer pulls out his ebay key, can you do this also? Coded remote fine, cut mine fine, cut his..... sounded a lot harder. Went to code the keys, ours in and out ignition fine but his would go in 1/4 of the way and jam. So if this is outside our shop, and numpty customer forces they key in and damaged the wafers, he aint going away quickly and certainly not quietly. We have seen this a number of times now and is why we finished cutting ebay keys.
Also you are most likely cutting the customers key, who then goes to a beer money £15 ebay special software to get the key coded.... So you are helping the sod who is under cutting you, not invested like you have and taking the risk of cutting the crap key?? They will send "their" customer to you, for you to cut it and do you out of the "proper job" We had this numerous times. Garages who we used to do work for using there own recently purchased software but want us to cut the keys and sell the key cheaper?
I did have the outlook of £15 for cutting is better with us... but don't see many positives for the potential fall out, and helping others to avoid using us for a full service.
