🔧 General Questions
🔌 Engine starts then shuts off after remote start
Missing or improperly programmed immobilizer bypass module (Passlock for GM, PATS for Ford).
⚡ Remote start does not crank at all
Check starter wire connection and chassis ground. Verify with multimeter.
🔋 Push button start not responding
Check fuses, main harness connection, and ground. A blown fuse is most common.
🔐 Door locks not working after installation
Incorrect polarity configuration — some vehicles require external relays.
📡 Poor keyless entry range
Keep antennas away from metal and high-current wiring. Relocate higher in dash.
🔄 Remote start stops after a few seconds
Security interference, incorrect brake wire, or tach signal not learned.
🚗 GM / Passlock Questions
🔐 What is GM Passlock?
Factory immobilizer on 1995-2005 GM vehicles. Without bypass, remote start won't work.
⚠️ My GM starts then dies after 2 seconds
Classic Passlock activation. Install compatible bypass module (XK04, Fortin, DEI).
💡 Security light flashing on dash?
Immobilizer issue — missing, unprogrammed, or faulty bypass module.
🚗 Toyota Questions
🔐 Do Toyotas need a bypass?
Many 1998-2010 Toyotas have transponder immobilizers. Some trims require bypass.
⚠️ Push button lights but engine won't crank
Check brake input, starter wire, ground, and immobilizer bypass.
🔍 General Troubleshooting
🔧 Push button does nothing at all
No constant 12V, blown fuse, poor harness connection, or weak ground.
🔐 Door locks work backwards
Reverse lock/unlock polarity. Some vehicles need external relays.
📡 Remote start range very short
Relocate antenna higher, away from metal and high-current wiring.
🛡️ Do I need professional installation?
Yes, strongly recommended. Wiring varies by year, trim, engine, options.
