Code alarm CA545

Hi, is it possible to program the LCD remote from the CA645 to the CA545 alarm?  If so, can you give me directions?  Also, how do you adjust the sensitiviy on the shock sensor?  Thank You!

yes you can do that.  i've done it to a buddy of mines alarm just messing around.  First you open the door put the keys in the ignition andc turn them to the on position and push and hold the valet button until it beeps. i think it will chirp three or four times and then push any button on the remote to program it. i dont really remeber how to adjust the shock sensor but i know its built into the brain so you have to adjust it with the valet button.you will need the instructions on that. 

cool, thanks a lot!!

Good lucktrying to set the shock sensor. (thats why we got rid of Code).The 425 brain has 64 setting on the shock sensor and its a pain in the a$$ to adjust. My uggestion is to turn the sensor all the way down  since it cannot be turn off and get an external one. This will solve any problem that you currently have

How to you connect an external sensor to it?

the lcd remote will still tell you about whats being done to the car. if the shock sensor is triggered then a hammer will show up. and the shock sensor is a pain in the butt to get working right.  i had to buy an extra shock sensor to plug into mine to keep it from going off all the time.the brain itself has a sensor built in it but you might as well turn it all the way down and put the external one on there. i dont know where you would find one since circuit is getting rid of code, but you can try the website.
