It's a good thing that it's an easy diy job cause interestingly enough most shops (in my area) won't go near it with a ten foot pole ... apparently a few peeps had issues with them and it fried their whole nav system and came for their nav replacement money to the installers.
For the record, I was never told which company's lockpicks did this and which models, but in these parts most car audio shops now stay clear of them.
Also for the record I personally have never heard or read from anyone saying that this specific make and model lockpick has done anything other than that which it is built to do ... I'm just noting that personal installation might be the only option for many folks.
