Well I've had my car almost exactly a year (to the day) and it decided have a party in my garage overnight (I assume with the sexy red Honda motorbike) and not start in the morning.

Got in, turn key (no keypad lights), click click. Hmm ok, must be battery. Put the battery on charge, got it to 50% tried again, the keypad barely lights up and still no start. Gave up, left the trickle charge on and called a taxi.

Just got back to it now (3 days later) and the car starts, however the only light illuminated on the keypad is the letter "1" and is doesn't ask me for my code. When the car is running the number "5" is the only key lit. I'm assuming that the flat battery has caused it to reset and thus clear my code. I've got the security system manual, which is less use than a chocolate fire-guard and doesn't give any directions to setting a new passcode.

Am I right in thinking this is the cause? And if so, how do I go about setting a code?

Your alarm has gone into valet mode due to low battery voltage, replace your vehicle battery.
Use up all the valet mode starts, and it should start to work again properly.
Be warned though, you may need to take it to a dealership for a master code reset if you disconnect the battery.

Only a dealership can change the user code.

ah-ha! That makes much more sense! Yeah I'll definitely be replacing the battery, I was always taught to replace a battery at the first sign of failure.

Thanks for the help! :-)

1) Loosen the battery terminal bolts.
2) Put a jumper pack on the terminals.
3) Pull the terminals off the battery with the jumper pack still attached.otherwise you will have to tow the car to the get the brant reset.
4) Remove battery and work backwards and you are done.
