area.  
PIN Code  
Each Cobra 8185 Alarm System has a  
unique PIN code which can be used for  
Emergency Disarm and is required,  
together with one of the emergency  
override touch keys, for programming  
replacement or additional radio keys.  
Your PIN code is given on the card  
supplied with your Cobra 8185 Alarm  
System together with the serial number of  
the system itself. Please keep this card in  
a secure place - not in the car - and also  
make a note of these numbers for any  
second driver’s use.  
All round protection is ensured with:-  
1. Passenger compartment protection  
using ultrasonic sensors or optional  
microwave sensors.  
2. Multi-circuit engine immobilisation -  
operates immediately the system is  
armed, or passively 60 seconds after  
ignition is switched OFF and the driver's  
door opened, or 255 seconds after  
ignition OFF if the doors are not  
opened.  
Without the PIN code and emergency  
override touch key no additional or  
replacement radio keys can be  
programmed into the system.  
3. Peripheral protection to doors, boot  
and bonnet using direct contact  
switches.  
4. Personal protection - remote control  
‘panic' button on radio keys.

Radio Keys  
The security system is operated by remote control radio keys. Two radio keys are  
supplied with each Cobra 8185 Alarm System. Always press the button for a full ONE  
SECOND to allow the whole code to be transmitted. The small LED on the radio key will  
flash whilst the button is held down. The Radio Keys should normally operate up to  
5 metres from the car but range can be affected by other radio signals in the vicinity.  
The Radio Keys are powered by a long life 3v Lithium battery  
(type CR2032 or equivalent). With normal usage a new battery  
should last between 3 and 5 years. Replacement batteries can  
be obtained from your Cobra Dealer.  
Low Radio Key  
Battery  
Indication  
If the small LED on the radio  
key flashes irregularly or only  
once when the operating key  
is pressed, instead of flashing  
continuously, this indicates a low  
battery.  
3. Wait for 10 seconds before inserting the  
new battery, ensuring the correct polarity  
(+ sign upwards) and holding the battery by  
the edge.  
Battery Replacement  
4. Close the case firmly making sure locating  
studs are correctly positioned to ensure a  
waterproof seal is made.  
1. Open the case as shown in the  
diagram - levering the two sides  
apart in the area marked OPEN on  
the key case.  
5. The remote key should now operate  
normally, but it may require re-  
synchronisation with the main control unit.  
2. Remove the old battery as shown.  
Testing the Remote Key & Re-synchronisation  
If, at any time, the remote key does not operate the system, stand close to the car and  
press and hold down both buttons until the LED on the remote key goes out -  
approximately 10 seconds. Release both buttons - the LED will come on constantly. Then  
press button ‘A' for approximately 1 second - the LED will flash - this should complete re-  
synchronisation.  
In case of difficulties please consult your Cobra Dealer.

Passive Immobilisation  
The System will automatically arm the  
double immobilisation 60 seconds after  
the ignition is switched OFF and the  
driver's door is opened. If the doors are  
not opened the delay is extended to 255  
seconds after the ignition is switched OFF.  
The radio keys for your Cobra 8185 Alarm  
System have a ‘protected self-learning'  
feature which allows up to four Radio Keys  
to be programmed into your system by  
using its unique PIN code in conjunction  
with the electronic touch keys.  
l The LED will flash.  
All existing radio keys and touch keys  
must be re-programmed at the same time  
as any additional or replacement keys are  
being introduced to the system. Your  
Cobra Dealer will be able to carry out this  
procedure for you.  
It will not now be possible to start the  
engine, but in this instance the doors will  
not lock and the windows etc. will not  
close. The door trigger circuits and interior  
sensor do not arm.

8185 Alarm System in the event of lost or  
damaged radio keys. If your car is locked  
use your door key to enter the car and  
touch the Emergency Override Touch Key  
on the contacts of the touch receptacle -  
this will disarm and de-immobilise the  
security system. If the system was fully  
‘armed' the siren will sound until
