I charge a flat rate and sometimes a litle more depending on the customer. A basic remote start w/o keyless starts at $125 +$40 for a bypass. A remote start w/keyless starts at $199 +$40 for a bypass. If the customer wants to add things like trunk pop and horn triger depending on the customer i will charge between 10 and 40.... Steal from the rich and give to the needy. Also make sure you have a policy on returning, return of product only - no return of labor. If you dont do that you can get screwed out of a lot money. Lastley, look into libaiity insurance for damage claims. I f*ed up a panel in honda once the dealer wanted $200 just for the part luckly the shop had insurnace to cover it.

A kid that I used to work with connected (dont ask me why) the illumination, dimmer... all the orange wires on a honda deck harness together.  the lady turned on her lights in the parking lot and smoke filled her car.... anyway $1600.00 for honda to fix not to mention the cost of the rental car.... insurance claim for sure

Well once i was working on a 2001 Dodge dakota and i shifted it into netrual and hit the 4wd selector went to shift it back into park and stuck in reverse and the engine reved and flew back into the garage door. A easy 2grand of damage from that one. They said i had something underneath the brake pedal pushing on the gas, that dosent pan out because i had my foot on the brake to sh*tf out of park and it didnt do nothing then.

A guy in my shop a few years back didnt fuse the +12v wire on an alarm in an s-10 pickup....well, it shorted and because he put it to the fuseblock and to the HOT side , the  truck caught fire while the owner was in McDonalds drive thru---he ordered his meal with a fire extinguisher...ha ha...the truck came back in covered with white halon residue in the whole interior, myself and the boss worked on it all day to reconstruct the dash , ductwork and wiring......laughing the whole time....the installer that caused it was nicknamed "sparky " for about a year........anyway, sometimes stupid mistakes are made, you never know...get the insurance....
