Tilt sensor add on to oem
Hey all, looking to add a tilt sensor to our OEM alarm. I've become a little paranoid and want to add this without having to do another alarm and carry another key fob. For right now this would be my only piece of mind on top of the oem security. I was thinking of upgrading later to the Viper alarm with 2 way AND a Lexus key card so I can just vary the card and the alarm.
Any recommendations?
I've checked with one local shop who was pretty informative. He stated that our alarm systems brain only has so many inputs (kill switch). He stated that I'd have to get, or SHOULD, get an after market alarm with a brain with multiple inputs. He stated not to do the splicing or use a relay because it'll really be messing with the internals and can cause false alarms.
I've searched and a couple of old threads, even a DIY thread shows a DEI tilt sensor can be added on by modifying the current oem. Is this the only case to add a sensor? Has anyone done it recently?
Thanks in advance for the input.

I have the Viper 5902, and it works fine -- remote kinda sucks because it's too easy to press. The 5904 is the newest model I think, but same remote and practically everything else.
I would be more critical on listening to what someone has something to sell me says. The things you will gain from after market is 2 way alarm and remote start, not inputs (whatever that is) -- of course that comes with an extra remote.
The DIY is fine; unless you got a 2014, I don't imagine anything would have changed other than wire colors -- probably still the same with 2014.

Thanks for the input! I've seen a setup with the same alarm and then they purchased and programmed a Lexus smart key CARD. They carry it in their wallet and have the two way remote with them. That's ideally what I want but the budget doesn't see to it.
I figured for now, just add the tilt sensor with the oem. Thereafter, the viper alarm.
Any other suggestions?

My stereo/alarm shop added a glass breakage and tilt sensor to my factory system. The DEI tilt sensor gave me an issue and we replaced it with a new one an it gave me the same issue (not able to arm if I remember correctly) so I just removed it completely. So it is possible to do. And it's cheap.

Thanks for the input...Hmmm well it is possible but then you mentioned the arm wouldn't work. No point to install if the car doesn't arm? It seems like an aftermarket alarm is the only solution. =T
Thought I'd be able to just install pieces rather than a whole

You can install the pieces alone, I did it.
You can install a glass break sensor and also the tilt sensor, all you need to do is when they are triggered you send a signal to the car that makes it think a door opened.
My setup cost me like 60 bucks for gear and about 4 hours to install.

it looks like I may have to go for an aftermarket alarm RATHER than a hit or a miss with the DEI Tilt sensor.
Ultimately I'm just looking for a Tilt sensor to piggyback onto the OEM alarm.

You do know that the DEI Tilt sensor is what most alarms will use?? You get the standard alarm then you can add in the tilt sensor... Most of the time the installer will use DEI.

My question was if the two options above are the only ways to add on the "add on tilt sensor". One route is the "correct" way (2 key fobs) and the other is a "modified way" (one key fob). Each has it's plus and minus points.
I see that Vapid2323 you posted last on the DIY thread, how did the DIY go for you? Are you carrying around 2 key fobs?

Yes. It's an "ADD ON" item. I'm completely aware of the "add on" sensors for a car; back up battery, glass, noise, movement etc. Most installers around my area or any area use DEI; i can even pick it up on amazon for 25 bucks. It's a matter of either pairing it with an aftermarket alarm (which will have one carry 2 key fobs, OEM and aftermarket), or with the OEM (a splicing and piggybacking setup).

As for the install, the hardest part was trying to convince the guys at NAPA that I was building a Security system. They just kept telling me that the relay I wanted should be in the 'kit' I bought lol. They just could not understand that I was literally BUILDING the security system >.<.
I did have to convince them to sell me a relay from a BMW.
As for the actual install, the hard part was most definitely getting the center vents out. But after that everything went super smooth. Just make sure you take your time and you should have no issues.

Please refer to the wiring diagram below. An essential part that's needed is a piece of 10"x10" cardboard -- you can cut it out from a box, but it must be 10" square; if it's in-exact, it may cause false alarms. If it's impossible to get an exact length cardboard, you may substitute your missing length with additional weight. For example, if your cardboard is only 10"x9", add 10oz of copper/iron in the 9" side. However, this is not 100% supported and might not work as well as an exact sized cardboard. You will also need a bell; any bell will work but not a cowbell because we don't need any more cowbells. Finally, get a blue string of appropriate length and attached to all 4 corners of the cardboard with the cardboard glue to the backseat. The strings should be tied/merged into a single string while still inside the car. A hole will need to be drilled and have the string pass through the car. Optionally, if you don't want to tied the 4 strings together, you may drill 4 holes in the car. The last step is to set up the bell inside your house, preferably next to your bed for maximum effectiveness. Depending on your house setup, you may also need to drill a hole in the wall. Tie the string to the bell to arm the system. You can test out the system by lifting your car; the bell should chime.
