Reasons Why a Lexus RX400h Key Won’t Turn
There are several potential reasons why a Lexus RX400h key may not turn in the ignition. Here are some possible causes based on the information from the search results:
1. Binding Steering Column/Lock, Ignition Switch, or Key Issue: The key not turning could be due to a binding steering column/lock, ignition switch, or an issue with the key itself.
2. Electronic Ignition Lock Failure: The Lexus’ ignition lock is a safety feature that, when it fails to read the steering column and/or key, can prevent the key from turning.
3. Pressure on the Key: Sometimes, when the car is parked with the wheels turned to one side, it puts pressure on the key. Turning the steering wheel a little more each way while turning the key may release the pressure.
4. Key and Ignition Lock Cylinder Wear: Worn out key and/or ignition lock cylinder could also be a potential cause for the key not turning.
Possible Solutions
Based on the information provided, here are some potential solutions to address the issue:
1. Lubrication: One user mentioned using a shot of Liquid Wrench Dry Lubricant into the key opening and hitting the key opening with a blast of compressed air to resolve the issue. This may help if the problem is related to a lack of lubrication.
2. Replacing the Tumbler for the Ignition: It’s suggested that replacing the tumbler for the ignition is a relatively easy fix. Using a new key accompanying the new ignition cylinder is recommended. Additionally, Lexus recommends replacing the entire key set as a repair for this condition, which may be covered under the Lexus Comprehensive Warranty.
3. Seeking Professional Assistance: If the issue persists, seeking assistance from a professional locksmith or the Lexus dealership may be necessary. It’s mentioned that locksmiths can often program remotes for less than the dealer.
It’s important to consider these potential causes and solutions when dealing with a Lexus RX400h key that won’t turn in the ignition. If the issue persists, seeking professional assistance is recommended.
