Shops won't sell me an alarm

True, That's one receipt you need to keep in the vault.  I wonder how they will fix a car that burned to the ground. Just kidding. Nevertheless I found a shop that would sell me both. Fair price. He even said,  "you know I shouldn't be selling this to you right".  It's probably not worth losing your DEI products for a small profit on one alarm so most shops probably won't chance it; but I still think DEI is stupid. They should just void any liability if not installed by a certified installer, not refuse to sell it.  Thanks to everyone who pointed me in the right direction. Will install this weekend.

as a shop owner doing exactly what you suggest i have this to say:   most shops don't want to clean up customers sloppy install jobs.... it's a pain in the a** to sift through spagetti trying to figure out what the heck they did wrong....

and i'm sure that the reason DEI doesnt want hack install jobs done with their products is because it reflects poorly on the product... for every 1 customer who grumbles about a sloppy install or product problem 10 potential DEI customers look at another product.....

i guess DEI's philosophy is similar to my store philosphy here.... Do it right or don't do it at all !!

Yes they do. the mark up on security systems and remote starters is insane because the labor for the basic installation is included in the price. All big box retailers do this, because 90% of the people who buy these types of products NEED to get them installed.

have you ever read the tag?  A MATERIALS FEE OF $4 APPLIES, EXTRA PARTS AND EXTENSIVE LABOR EXTRA.

thats why next to the FREE tag it has the little * next to it, for see notes below.  I am an installer there so im pretty sure i know how my company handles selling remote starts, keyless entry, and alarms.
