What is the best car security alarm?

Auto Security Alarm system (Viper 550ESP) in bad state (Car inoperable)?

• I bought this pre-owned 97 Honda Accord SE that came with Viper 550ESP alarm/auto-start system. Lately, I'm noticing that the alarm system is behaving rather erratically and its getting progressively worse. Some of the problems I have seen have been: - 1) The system gets armed and then I can't disarm. The alarm goes off, and I'm playing trial and error. Finally I get it to disarm, but I really don't remember the sequence. 2) This weekend, I couldn't get it to disarm. The horn doesn't blow anymore but the headlight flashes and its still armed. Finally I got it to disarm to the extent that I could start the car. For a while I was extatic, and gave the good news to my wife. But then I realized I can't shift the gear out of Parking. Damn!! Seems to me that the system is in bad state. I can remotely and manually close and lock the doors. But I cannot set off the alarm. I'm towing the car to a dealer tommorow. Any idea how costly the fix might be? Any feedback will be appreciated

• Answer:

  disconeect the battery terminals (both) replace the battery in the remote. That should take at least 10 minutes. Now hook up the terminals again, this resets the system, and the new battery may cure the problem.
