from 1-5 (5 being the most difficult) which cars would you consider the most difficult or frustating to install remote/alarm/keyless?

Weaksauce..... they are all easy if you want them to be! But, just to play along, here are my kryptonite cars:
1) 2006+ Saab 9-3. No bypass, no modules available at all. Gotta do it the old fashioned way..... DMM and smarts as there is zero tech info either! (I have one out there and working. Even the dealer was shocked)
2) MB newer than 2005. Not fun, many are impossible. We don't touch 'em
3) No 3, 4, or 5. Everything else on the road is pretty much not that bad to do at all.
Want to have some real fun? Do an alarm on an older Lotus Esprit. You will be begging to work on a VW (which are about GM easy if you want them to be)

Original post mentioned a scale 1-5, 1 being the easiest, and 5 being the hardest. So his 95 accord listed as a 1 is considered easy. Jonathan

Re-read the post, and I misunderstood it as well  should be: "Top 5 hardest cars, 1 being the easiest hardest car and 5 being the hardest hardest car." Jonathan

Either way a 95 Honda Accord should not be on the list of the 5 hardest cars to install an alarm. That is like saying a 1986 Honda CRX is the hardest vehicle to install a radio.

5- audi A8 (prior to CAN system) 4- benz 500 SL (prior to CAN system) 3- 96 - 99 doge durango ( not really hard but just a freeking problem car, hate doing any type of alarm/starter on thee) 2- rolls royce silver shadow (or something to that effect) or anything else that's old expensive and falling apart. 1- any ford with the pellet thing. i hate that pellet with a passion it's almost always a sure comeback. ------------- life is a comedy to think, a tragedy to feel

If you are that unsure, then pay a proper shop to put it in.
Seriously.

I don't really have a top 5 however I will say that the hardest I have ever done is an 09 Murano, the only tech info I had to go on was "It's mostly the same as an 07 Altima" most of the ignition wires in that car go under the hood and the wires for the locks have to go through door molex plus it has the no key needed intellikey, no bypass made for it (the XK07 mostly works), and to top it off the wires that do not go under the hood go to the BCM which is behind the instrument cluster and has, no exaggeration, about 1 inch where you can tap and solder about 10 connections. That car is a pain in the butt, however I can tell my customer that he is one of the few out there with a rem start on his

Suzuki Grand Vitara, Corolla, Camary, Civic, Accord, everything else besides these vehicle are difficult in my book. ------------- Be careful whose advice you buy, but be patient with those who supply it.

Chryslers. Damn difficult before XKs came to be. But recently the 08 Wranglers have been a damn thorn in my side. Just did a Viper 5900, 4 spkrs, 4 channel and lemme tell ya, get an impact wrench to take out the seats. Or roid it up first.  ------------- BOOSH!!

I'd say my hardest alarm install so far, is the 08 Dodge charger cop car, I got stuck on. It needs about a million resistors and relays for every hook up.

well take a look at the tech info on it. tag and test all your wires. if this is your first install, make sure you set aside mininal 3 hours. it could take you up to 6 first time.

Ok nevermind it was actually easy. Just use a bunch of relays and resistors for the 08 dodge chargers

From my side of the pond, Late 80's 5 Seires BMWs where you had to go the rear end for lock, deadlock close door and trunk contacts. Smart Coupe any post 2005 Audi or Mercedes the so called CAN specific systems from a certain company just don't work properly, Lotus Elise, same reason as Smart Coupe, I think it was a Pontiac for a while, stand them upright on their tails and you could work them, I've not done the latest BMW's but warning, to change the subject, if any one is doing Parrot kits or similar in cars with the latest sqare Euro-plugs, called MOST or quadlock, don't use the adaptor leads, they chop and change, BMW changed in 2005, use an earlier adaptor and you've lost the radio tuner, the only 8 leads standard to all are the speaker outlets. If it mutes, chop and insert the front speaker connections from the kit, if it doesn't do all 4. Easiest, 90's Japanese. Can't do US except Mustangs, ain't done the course.

Gary, don't you ever sleep? Mind you I was watching Die Hard 4.0 and I'm so anal that when Bruce Willis was attempting to hot wire a late 5 series, the reason he failed was that the colours were all wrong! Someone phoned me and asked what she could do in future because her E class was stolen whilst she left her key in the car with engine running, whilst posting a letter. I said short of Blackjax, she should kick herself up the back passage every time she left the car with the key in it. You lot should thank your lucky stars you do't get French cars, Italians or Protons from Malaysia (3 gen old Mits, think Lancer or Colts from the early '90s) Take Peugeots, don't use colour codes, just tiny writing on the wire, change colours every few months, 2 x ign1's, join them wrong way round on a remote start (either will work for immobilisation) and you've lost the facility to hit the footbrake to exit auto-start mode! Radio is linked to engine management and to avoid all sorts of problems you wire acc from new radio to hard acc at ign sw or fusebox. The others just fall-apart, eg switches or trims when you work on them, panels don't go back properly when you put them backas in Fiat and Alfa, you had to pull half of the wing (fender) off a Fiat Coupe to get through to the engine bay etc etc, Peugeots, dome light front, purple = 12v+, grey = door contact; hatch grey = 12v+, purple = hatch contact!Peugeot vans, load area light is switched from driver's door( NB the colour even changes between light unit and switch contact)! New Audis all CAN and everything hard to get at, think ign switch wiring or steering column cowl on Mk IV Golf/Jetta, the smaller Polo and the Transporter van use a multiplex lock and window close via a 1k resistor, the bigger cars use low current neg.!Also need separate door contacts AND diode blocking on most 'cause of the bloody Siemens body management every EU car uses.

Did I remember to add the nasty late VW Polo? 4 doors trunk and hood all to be diode blocked and doors diode joined all whilst working upside down, the removal of the steering column shroud is similar to making love to a porcupine, just to get to the ignition leads, multiplex, 1kr on the unlock going to a thin blue/white in the door lead which is buried in a horrible thick annealed rayon tape, on earlier versions when you extended the lock pulse you got total close, on new ones same lock/unlock wire but no total close!

"Someone phoned me and asked what she could do in future because her E class was stolen whilst she left her key in the car with engine running" LOL howie. Yeah shutting the car off and taking the keys with you is always a good preventative measure. Side note, Puegeots and Freightliners must be made by the same ppl. Was putting a phone in one the other day and the best part of that day was scaring the hell out of my coworkers with the air horn. Every wire the same color, and no easy writing either 2305 might mean ignition to whoever builds them but to me its just the time i got off work that night after taking my multimeter to EVERY single wire in the vehicle. SIDE NOTE: When working on big trucks not all "wires" are wires. Fortunately I remembered that instead of multitesting an air hose. ANYWAY... on with thee reason for the topic, lol. 5 - DODGE Why: I hate resistor/relay wiring. 4 - DODGE - Why: The ECM on the bottom of the engine but on top of the oil pan where you can only see it laying on the floor but lose sight the moment you put your arms up to reach it is a horrible place for tach wires on deisels. 3 - Id like to say dodge again out of spite but probably FORD Why: like dodges but not as bad 2 - HEATED SEATS wiring before controlled by data. Why: Wires through door boots is crap and soldering to contacts on an expensive control board makes me nervous. 1 - RANDOM VEHICLES I havent done before Why: Just the lack of familiarity. Not necessarily hard but they take longer because you have to take more time figuring all the quirks and where the screws and clips are.
