Hi,

A couple of ideas:

• the primary concern is intermittent/false trigger of security alarm - check/clean/replace triggers mainly the door switches (faulty due to corrosion/rust, any constant rain lately? car wash?);
• check key/remote for stuck buttons, damp/condensation underneath the rubber pads/keys;
• disable original wire to the horn. Hardwire a new horn relay, new wire to the horn, new wire to the hurn button on steering. Even if alarm falsely triggers, horn would not sound off yet retaining use of the horn. Most competent auto electrican should be able to do this.
