Hi,

I'm having problems with my alarm. It doesn't register my key presses, mainly disarm. I have to press it many times before it will disarm. I've tried resetting it and reprogramming the remote. That hasn't helped. Using the valet switch to disarm it still works. Anyone on this forum in Victoria who can service these alarms? Getting very annoying when I have to stand at my car pressing the remote over and over again.

Hey. its a viper what else can I say. They are only useful as sinkers when you go fishing! Chuck it out and get e real car security product.

thats a bold comment, directed electronics make some of the best products on the market !!!! if you have the talent to wire them up right ?, failure rates are extremeley low which is why they have a lifetime warranty on most (not batteries ) parts , 99% of the time bad wiring job or remote thru a washing machine is the issue.

take it back to the place that installed it ??? they would sort it out quickly

first guess, no antenna connection or its been cut/taped on steel after someone worked on the car ,which = no range on remote, second, lost programming by fiddling around with a few things with the key on , is it a new remote??? changed the remote or car battery lately, remote battery is it in the right way?

a newer viper won't unlock if it see's mutiple alarms in close proximity being armed or disarmed. the upper models will vibrate or chirp the transmitter when that happens(anti code scanning protection)

sometimes the on off button gets mashed inside by you pushing on it too hard or crap in your pockets, if it can be unscrewed

have a look at it on the inside , the little pin behind the button , mushroomed ??? or missing ??

does it work by pushing the little rubber button with the case off? if so buy a new case or remote

if you have two remotes try the other one??

if not does it have any error code beeps or flashes ?

might be a scrambled brain if you jump started the car ? but if a DEI Authorized pro installed it ?? DEI will swap the brain no fuss most of the time

Sounds to me that there are alot of things that could go wrong with a Vyper...Not to mention the countless emails over the past decade for the same type of problems, but don't worry Brant Alarms are still winning in the category for most unreliable car alarm.

I got someone on this forum to install it. I've tried a second remote so it's not a remote issue. I just need someone who works on alarms to have a look at it for me.

change the batteries onthe two way unit and make sure its set to user 1 on the remote. that is 90% of the issues with those. the otehr 10% has to do with antenna placement and install.

      You are perhaps suggesting that it is not a super car? Well....it's not an AU.

      Dropped the MX5 of this morning to get the hardtop colour matched and some PDR done, they are also going to give it a buff to remove some "stubborn" swirl marks and light scratches in the clear coat Over the last few months the poor little thing has copped some shopping centre car park abuse, I try to not park in them, but hitting Westfield's a few times over the last few months has taken its toll, nothing really bad, but enough of a trigger for a "while we're in there" thingie  Once it's back and all the one colour, with a few dents and mark's removed I'll give some of these products a go and see what they're like

      A locally delivered Infiniti have remote start installed but don't come with the remote start key. You need a new remote start key and they just need it programed. And this is different to making/programing a new key that just starts the car.

      Cheers, and cheers for sharing so much of the build and also sharing the glimpse of what turns out to bring a lot of us poor decision makers together haha.  I do recommend learning more about how to manage it, if not considering getting a  formal diagnosis.  The discussion with the psychiatrist I got my diagnosis through was quite eye opening, things I'd not even considered to be ADHD related and hadn't mentioned were things she asked about out of the blue and were common themes with people with my flavour of ADHD.   It's not a label for people who are hyperactive and ill-attentive, there's more to it than that and some of it can be much more challenging or damaging - though there are of course two sides to the thing, and a lot of the stuff we have to go through and work on to live with it make us effectively "better" at other things as well. Aside from the fact that there is some argument I could have a bit of ASD seasoning in there (came up during the diagnosis, and neurodiverse things seem to not stay as a cookie cut) I suspect you need to learn more about ADHD if you are puzzled about how hyperfocus could possibly apply.  I *do* personally use "superpower" with quotes deliberately, but it's 100% an ADHD thing due to the exact reason that lack of focus is also an ADHD thing... Loosely speaking the inattentive side of ADHD isn't the inability to focus, it's the inability to control where the focus goes.  Not being able to sleep because brain is more interested in thinking about a stupid thing I said to a girl I liked 30 years ago, not being able to focus on work because my brain is more keen on putting together the torque management strategy we're going to try out with a drag car next weekend, not being able to focus on a conversation with someone I WANT to listen to and respect because there is a flickering light in my peripheral vision.    If I could just stop work and build the torque management setup right there and then I'd not hear anything else until it was done.
