I was having problems with my OEM alarm on my 99 Acura 3.5RL. It would go off randomly for no apparent reason, without any apparent trigger or cause. After much googleing and many forum searches on many different sites, i came to the conclusion that my hood latch sensor had gone faulty and decided to "jump" the 2 pin connector.

Feeling that i needed better car security, i decided to have my python 871xp installed with the 555d bypass module. unfortunately the car would not remotestart although the other functions worked perfectly fine.Under the advice of my installer, i plugged the hood latch sensor back in. This however did not solve any problems i had with the 555d, so i purchased the TBXKEY and had that installed with great success.

My only problem now is that when i try to remotestart the car, the OEM alarm will go off occasionally, mostly when the car has been sitting for a few hours (4 or more) or when the weather is cold. I have tried to jump the hood latch sensor again but doing so only causes a zone fault detection by the Python 871xp, therefore disabling me from remotestarting the car.

Any and All input is appreciated!
Thanks!

a new development is that now since me and my teacher have been trying to diagnose the problem via checking the voltage to the switch through the harness and checking the health of my battery, and everything seems fine. Now the alarm doesnt go off, but if the car sits for a few hours, (say 2-8 hours) either:

a) the oem alarm will go off and the car will remote start
b) the oem alarm will go off and the car wont remote start
c) the oem alarm wont go off and the car wont remote start
or more rarely
d) everything will work properly, the oem alarm wont go off, and the car will remote start

(a) usually happens in the morning after the car has been sitting all night (4+ hours at least) therefore forcing me to disarm the car and rearm the car, all while remotestart is working and operational

(b) happens more often that (a) also in the morning, after the car has been sitting all night (4+ hours at least) therefore forcing me to disarm the car and rearm the car, all while remotestart is attempting to remotestart the car, but not able to crank the engine (just clicking and flashing of the remotestart module, but no starter crank)

(c) happens randomly, remotestart is attempting to remotestart the car, but not able to crank the engine (just clicking and flashing of the remotestart module, but no starter crank)

(d) happens more likely after i drive the car to a destination, and then return to the car, and/or remotestart within the hour of arriving at my destination


anyone have any ideas?

Im going to say that more than likely you are going to have totally disable the factory alarm. Factory setups do not like aftermarket products in your case remote start/alarm. I ran across a few cars with problems such as yours do to the customer wanting to maintain the factory keyless entry or other issues while working for Circuit City roadshop back in the day. The resolution was to totally remove or disable the factory security system, after that all was well. Now I do believe there is brain similar to your python, the location??? I am unsure as of current, because I havent even attempted such a project on my RL. Thats due to time, weather and not wanting that headache right now. I dont know if I was any help but hopefully this lead you in the right direction. Hit me back with any updates good luck bro!!

If i disable the factory alarm might i have to have the aftermarket alarm rewired?

also yesterday and today, i tried to remotestart the car only to (b) happened again, so i took out the key in the bypass module put it in the ignition and started the car, then i put it back in the bypass module and remote started the car just fine... but i know for sure that if i let the car sit for 2 hours or more i will have problems remotestarting the car again

im starting to get really confused, i dont know where to begin troubleshooting the problem...

The Good news: After adjusting the key in the bypass module and adjusting the antenna around the key cylinder, the car remote starts now. the alarm doesnt go off at random and i think i may have pinpointed the problem to the trunk latch sensor and not the hood latch sensor because when i close the trunk every once in a while the python alarm will indicate a fault in the system...

The Bad news: when i remote start the car the OEM alarm will still go off... and the car doesnt remotestart in the morning which is when i want it to start the MOST! (u know, warm up the car on a cold day!)

the car remotestarts fine after i have ran the car for a lil bit even about 3-4 hours later, just not more than 4 hours later...

for the last few days the OEM alarm hasnt been arming for some reason, (which is actually a good thing) and the OEM alarm was not going off when i remotestarted the car, but as luck would have it, today the OEM alarm started arming again. (hence the OEM alarm going off when i remote start the car)

my question now is, how do i disable the factory alarm and still have everything else work fine.
