Help-truck won't start, security system maybe?

My 2004 double cab sat for a few weeks and the battery died. When i installed the replacement, I noticed that the dash lights and blinkers flashed about 20 times then stopped even before I put the key in the ignition. It will also do this if I try to start it or unlock the doors.

When I try to start, it's totally dead. No turn over, no clicking, just the 20x flashing of the dash and blinker lights.

I got it used about 9 months ago and it had a simple aftermarket Bulldog (JBS Technologies) keyless entry/security system, but no remote or manual. I called Bulldog and they gave me a remote model number i could try (it worked), but didn't know what model number for the system. Also, I removed the siren when I first got the truck in case it went off since I didn;t know how to operate the system.

So, does this sound like the security system has disabled my ignition?
If so, how to reset? I removed the security module, but that didn't help me get it started.

 

Not saying this will fix your problem, but my old F150 had a similar issue.

What ended up happening is I would have to turn the ignition to ON then plug in the battery for it to reset the security system.

Maybe ask that security company again?

Good luck

 

It sounds like it, the only thing i can tell you is to look under on the driver side, on each side where your feet are, and see if you can find a little toggle switch. mine is small, steel, and does not look like something toyota would use, and thats the kill switch. you have to get in and when you turn the ignition switch, you flip it.
same sort of thing happened to me, one month after i got my truck, i knew i was going to need a battery and the one short period of cold we had last winter killed the battery so i walked to advance and got a new one, and it just f$&#&d my whole day up trying to figure out what was going on, I had never dealt with a after market alarm before. ( funny mine came from a ranch out in west texas, and the next day the org owner emailed me back about it and said the theft rate, they had to ....

 

Thanks for the advice, guys, that worked! I love the good side of the internet!!

 

Ugh, I get to try this out again! I found my own post when I Googled

 

on my nieces Malibu you leave the key in the on position for like 10 minutes until the yellow security light goes out then the alarm rests itself to your key.

I think there is some variant of this security reset with most cars but we explained ford and chevy so see if anything close to what we did works for Toyota

first thing I would do is just leave the key on for ten minutes and see what happens after that.

 

It worked Thanks again LBtaco!!

 

that's great, now you know the way to do it.

just a FYI, if it ever happens again it might be the key fobs doing it. they had an unannounced recall on the key fobs going bad and had to replace the ones my niece had.

they said that certain brand key fobs from 2000-2004 (not car brand but electronic circuit maker brands) had issues of "losing" recognition with the car so it thinks you have the wrong key and goes into lockout mode and nothing works. for here they just got new new key fobs and programmed em for her car, took about an hour total after they ordered and got the new fobs in.

none of this may apply to you but they told her the problem affects other car brands of those years too.

 

I'm having the same problem as the original poster of this thread. I have a key fob with the letters SPAV that I cannot find anything about on the internet but it's required to be near the ignition for it to start.

Is there a way to bypass this stupid security system?

 

Thanks so much for sharing this! I did the reset sequence but also had to push the unlock button on my fob. My truck alarm reset and it started right up!
