3 Car Secrets Mechanics Don't Want You to Know: Save Money & Your Car

CO2 Levels and Drowsiness

• 💡 Carbon dioxide buildup in a car's cabin, especially when using the AC on 'recirculate', can lead to drowsiness and headaches.
• ⚠️ Google states safe CO2 levels are below 1,000 ppm, with 800 ppm being ideal; levels above 2,000 ppm can cause drowsiness.
• 🚗 Driving with windows cracked or on 'fresh air' mode significantly reduces CO2 levels, improving alertness and safety.
• 💨 Older, less airtight vehicles may naturally have better ventilation, preventing extreme CO2 buildup.

GPS Trackers for Vehicle Security

• 📌 A magnetic GPS tracker, like the Spacehawk GPS, can be hidden in a vehicle to monitor its location.
• 📱 These trackers use a SIM card and cellular towers, requiring a monthly or yearly service fee, similar to a phone plan.
• 🕵️‍♂️ They can be used to track teenage drivers, verify a spouse's whereabouts, or monitor business vehicles.
• 🔋 Battery life can be extended by using economy modes, with updates ranging from every 30 minutes to 24 hours, lasting from days to months.
• 🌐 The device can track locations globally, with potential to track trips as far as Singapore.

Affordable Car Key Replacement

• 🔑 Getting an extra car key made can be significantly cheaper than traditional locksmiths or dealerships, with universal keys available for as low as $39.
• 💻 Programming these keys typically requires a diagnostic tool like an Autel programmer, which mechanics often possess.
• 🚫 Dealerships and some locksmiths may refuse to program customer-supplied keys, citing compatibility issues.
• 🛠️ For those without a programming machine, services like Tom's Keys can provide keys, programming machines on loan, and guidance.
• 💰 This method avoids the high costs often charged by dealerships and locksmiths for key replacement, saving hundreds of dollars.
