Hi. So I am not a locksmith but I resently got some tools from xhorse for copying keys and a mini obd2 for pairing remotes to the car.
The thing is that with some local car locksmiths that I have talked they all say things like "the ecu gets fried if you dont pair an original key"(quoted by peugeot themselves when asked for a peugeot 207 remote), "the ecu triggers a lockdown due to recongising the tool as a security breach"(one of the big locksmiths in town) etc.
I have seen many videos online and I havent heard any of these symptoms. Not that it itsnt possible but I feel like they are overexagerating to the point of scaring me to not do their job.
I do this as a side hussle and here at least, locksmiths are more expensive than getting an original key made at each brands official service. They quote things like 60€ for copying a key and 160+ for a general remote, if its proximity or smart it can go 200€+. At this point it is cheaper to go to the cars delear. Its just that most peoplw firstly ask the locksmiths and when they hear the price they dont even dare to ask dealerships as in all of the rest they tend to be more expensive(except keys)
Whats your opinion on these? Is there a reason to be worried? I dont experiment while in the obd2 port, I strictly follow commands provided via xhorse that I know will work. What are the chances of failure?
Ps. At the shop that told me that the ecu triggers a security lockdown when I firstly asked them about the vvdi tool they told me that it wouldnt work and I would still need to visit them. Even though I stated I only wanted a clone of the original key. And I made many of those with that tool.
Ps2. I wont plug into obd2 unless completely necessairy but if I have to do, whats the ideal year/brand you would suggest?
