Avital 3100LX 3-Channel Keyless Entry Car Security System with Alarm

Luxor: I had an old Viper ESP 500 alarm installed that I couldn't program any more for some reason. It also developed the annoying bug of passive arming with the door open. I about gave up when i found this inexpensive Avital alarm, which is actually made by the same company. It was literally a drop in replacement for the old alarm. I just disconnected the old one and reconnected the relevant cables on this one and voila! It works perfectly out of the box. This one has a connector for a horn alarm, but I had a siren installed already and works with it. The old one also had an external shock sensor you had to plug in, but this one has it built in. Best of all, the passive arming works as it should (active arming is the default but reprogramming is much easier!).

EJM: Está súper bien, solo el instructivo viene en inglés.

Logan : Bought it to replace an aging 3100 series directed alarm. New remotes would have cost the same or more as an entire new system. Such is life. Totally plug and play, very happy. Reused my old siren that was already there. I did call the customer service number so I could set the alarm to lock AS WELL AS arm the vehicle once the doors were open and shut. It’s just what I’ve always been used to, and they were very helpful in doing so, I guess I caught them on a good day? The other reviews kinda discouraged me from calling initially but I figured I’d give it a shot.

Roy: I bought this for my 1989 240sx before moving into a large city for some added security and peace of mind. The installation took about 3 hours. You'll need a test light or multimeter, wire stripper, soldering iron, heat shrink, electrical tape, and cloth harness tape for the best results. I highly recommend you do some research into what comes in this kit. You'll need to purchase a siren, door lock actuators (if you don't already have power locks), and a rely. I recommend the DLS 451M relay. It plugs right in and handles getting solid power to your actuators. The alarm doesn't put out enough on its own. You can also find all the info needed online regarding the wiring for your car. We live in a wonderful time where knowledge is free and easily accessible. It's worth skipping the wire splicers and soldering everything in for better longevity with the system. You can do it! Soldering isn't that hard with some practice.

Overall I'd buy it again. Does what it's supposed to with no issues so far. I've installed this on 3 cars now. If I have any I'll update the post.

NateNBeckie: As expected from Directed, the install instructions are less than stellar. They can claim that it's because these are made for "professional installation" all they want, but unless you're installing these daily, the instructions are hard to follow if you don't know what you're looking at. It's not hard or expensive to make proper instructions. The "professional installation" is just a cop-out. I've been doing car audio and security as a hobby for 30 years and even I had to double check what I was doing a few times to make sure I understood it correctly. One thing though. The instructions are VERY clear NOT to mount this to solid metal though because the shock sensor works best that way. Zip tie it to a big wiring harness, the shock sensor is plenty sensitive.

That said, this is a great basic system. It's nice that it has the starter kill and parking flash relays on-board. It's exactly what I wanted this time. THERE IS NO SIREN WITH THIS KIT, which is exactly what I wanted. Sirens are such a 90's item and they're not needed IMO. Honking horns are equally as effective and a ton less obnoxious. I just needed something to replace the lost remotes...

MarianoRM: Lo que mas me gusto de esta alarma es que es de muy buena calidad a un excelente precio en comparación con otras marcas del mercado. La he instalado fácilmente en mi auto. Tiene un buen diseño, los materiales tanto del modulo como de los controles son de buena calidad. Los controles tienen muy buen alcance, lo único que negativo, (que en lo personal para mi es insignificante) es que no viene con sirena, pero si trae una salida especial para conectar al claxon del auto, eso me gusto mucho porque se conserva la originalidad del carro. El envió me llego dos días antes de la fecha estimada. Otra de sus funciones que también me gusto es que cierra los seguros de manera automática después de arrancar el auto y los abre al apagarlo.
Recomiendo mucho la alarma hasta ahorita no tengo ningún problema con ella y estoy muy satisfecho con la compra.

J Smith: Exactly what I wanted and needed, and at a fraction of local shops cost. Was able to to add keyfob lock/unlock, and alarm to a vehicle that didn't have that from factory.

Photoleif: I wanted only lock and unlock for my 1999 4Runner, which like many people, I got used and lacking factory fobs. Mine was different from most in that it lacked the factory or dealer-installed receiver. There's no prewire vampires in this model-year, unlike in the mid-90s trucks, so it's a matter of searching endlessly online to find which wires, and where, to tap. (If you need help with yours, ask in comments.)

Once installed, the keyless entry does exactly what I wanted it to do -- gives me a key fob and the ability to lock and unlock. I didn't want any of the other bells and whistles like auto-locking, horn beep, bump sensor, all that. It's gonna be nice for people who need that, but I want to keep it simple. My coworker just got locked *in* his OnStar-equipped vehicle for half an hour while he called them to have them remotely disable the accidental panic mode and unlock it for him. And if there'd been a fire? Need I say more? Thus I unpinned all of the unwanted leads from the molex and went with the minimum four (gnd, B+, lock, unlock).

I like the little fobs, which are more compact than all I've used before. The buttons do need to be depressed...

Sam: Decidi adquirir esta alarma tras hacer una extensa revision acerca del fabricante (directed electronics), que es el mismo responsable de las alarmas viper. El auto es la version base de su modelo y no traia alarma, unicamente seguros electricos ( y cristales). Me recomendaban la viper, pero por todos lados el precio elevadisimo mas la instalación.

Si bien no es tan factible lo de la garantia, ya que el producto es importado, la calidad de la alarma es muy buena. Sus funciones son muy variadas y tiene 3 canales, lo que me permitió adaptarle un radar de doble zona, asi como el modulo de voz universal de la misma marca, y se instaló y esta actualmente funcionando sin ningun problema.
La alarma viene originalmente con un cable para conectarse al claxon del vehículo, ya que no trae sirena, pero se decidió adquirir una sirena debido a que se alcanzan mayores decibeles y permite que sea mas llamativo y por lo tanto, desanima al ladrón. SE compro una sirena de la misma marca por poco mas de 200 pesos, se conecto sin problemas, y esta funcionando al momento en forma adecuada.
Viene con las funciones basicas, como sensor de impacto, modo valet, modo...
