Alarm not engaging after detail cleaning

[sukru]

Yesterday I had my PT Cruiser it's much deserved detail cleaning, however after a few stops, I realized the alarm system is no longer working. When I lock the car, there is no beep, and the blue light does not start blinking.

I'm planning to go back to the cleaners, however I have a strong feeling that, they'll play dumb, or just ignore me, and will not accept the blame.

In that case, is there an easy way to fix the system myself, or shall I go to my dealer?

I have a '07 base model, with a Karr alarm system

They probably set the alarm to Valet mode. Read the instruction manual....

locate the valet switch.
To take it out of valet mode all you do is put key in the on position n hold the valet switch till the led turns off. it about 2-4sec that you hold it.

I hope this was right...

Somehow it fixed itself today. Very strange...
