Streetwise Keychain Alarm – 130 dB Personal Siren

130 dB at close range is the equivalent of a jet engine at 100 feet — physically disorienting and audible through walls and across distances. In public spaces, it's immediately attention-grabbing even for people who are distracted.

Personal alarms work on the same deterrence logic as car alarms: the threat of public attention and documentation. Potential attackers rely on being unnoticed. A 130 dB siren removes that possibility.

Keychain placement is the single most important carry factor. Tools that aren't with you don't help. A keyring alarm is with you every time your keys are with you — no decision required, no separate carry.

Replaceable batteries mean no dead-device failure mode. Unlike rechargeable stun guns that require regular charging, a battery-powered alarm is either fresh or in need of a $2 replacement. There's no ambiguity about readiness.

Yes — the alarm requires deliberate activation and does not trigger accidentally during normal carry.

Carry note: The activation mechanism requires intentional action to trigger. Normal keychain movement, bag jostle, or incidental contact will not set off the alarm.

Battery note: Uses replaceable battery cells (type specified in included instructions). Test the alarm periodically to confirm battery adequacy. Replace when volume weakens.

Hearing note: 130 dB at close range can cause hearing discomfort or damage with sustained exposure. Activate away from your own ear when possible during non-emergency testing.

1-year warranty. Keep the activation mechanism clear of debris for reliable triggering.

1. Attach to your key ring. Thread the key ring attachment and secure.
2. Carry every day. The alarm only works if it's with you. Keychain carry removes the decision.
3. When needed: Activate the siren trigger. The 130 dB alarm fires immediately.
4. Hold the activation. The alarm continues as long as the trigger is held. Release to stop.
5. LED: Activate separately for low-light navigation — locks, stairwells, parking decks.
6. Move to populated, well-lit area after activation. Call for help.
Test the alarm monthly (outdoors) to confirm battery strength.
