Maintain car electronic key systems through battery replacement, protecting from water damage, software updates, and proper storage. Regular maintenance prevents failures, extends key life, and ensures reliable vehicle access.
Modern electronic car keys are sophisticated devices requiring proper care and maintenance. Proactive maintenance prevents failures, extends key system life, and avoids expensive emergency replacements in Brisbane’s challenging climate.
1. Replace Batteries on Schedule
Replace key fob batteries every 2-3 years regardless of symptoms, and immediately when reduced range or delayed response occurs. Use correct battery types specified in your manual, wrong batteries cause poor contact and damage. After replacement, test all buttons thoroughly including boot release and panic functions.
2. Protect Keys from Environmental Damage
Brisbane’s heat, humidity, and occasional flooding threaten electronic keys. Never leave keys in direct sun (dashboards, windowsills). Use waterproof pouches in beach bags or during water activities. If keys get wet, remove batteries immediately, dry thoroughly for 48 hours, and test before use. Water damage is a leading cause of key failure.
3. Handle Keys Carefully
Electronic keys contain delicate circuits and components. Avoid dropping, sitting on, or placing heavy items on keys. Cracked key cases allow moisture and dirt ingress, replace damaged cases immediately. ABC Locksmiths stocks replacement cases/shells for most key types, preserving working electronics.
4. Keep Software and Firmware Updated
Some vehicle manufacturers release key fob software updates through dealership service visits or via car connectivity apps. These updates improve security, fix bugs, and maintain compatibility. Check during regular vehicle servicing whether key updates are available.
5. Maintain Multiple Working Keys
Always have at least two working keys. If your only key fails, replacement without a working key is more expensive and time-consuming. Create spare keys while you have working ones. This is far cheaper than emergency key creation from vehicle only.
