Toyota Land Cruiser Won’t Start with Smart Key?
We Fix Proximity & ECU Issues
Having trouble starting your 200 series Toyota Land Cruiser even though the key fob is working and the battery is brand new? If you drive a 200 Series or another modern Toyota Land Cruiser with keyless start, you’re not the only one facing this issue. A common and increasingly frustrating problem affects the proximity start function. The vehicle simply won’t recognise the key, preventing the engine from starting altogether.
At Sunny Coast Car Keys, we specialise in diagnosing and fixing keyless start problems in Land Cruisers across the Sunshine Coast, Noosa and Gympie. If your 200 Series refuses to start despite a working key, chances are the issue isn’t with the key at all, it’s with the vehicle’s ECU or proximity system. And we have the tools, knowledge, and experience to get it working again.
200 Series Proximity Start System Failure
The 200 Series LandCruiser is built for toughness, but its keyless entry and start system can be anything but. Many Toyota LandCruiser owners report problems where the vehicle no longer responds to the proximity key. Even though the key battery has been replaced and the buttons still work to lock and unlock the vehicle. You press the start button and nothing happens. No lights. No ignition. No error message. Just silence.
This is typically not a key fault, but rather a failure in the vehicle’s internal ECU or proximity detection system. The car essentially loses communication with the key fob, failing to authenticate it even when it’s inside the cabin. These faults can develop randomly, but are also known to occur after battery replacements, jump-starts, or minor auto-electrical work.
Toyota dealerships may recommend replacing modules or towing the vehicle in for diagnostics, which can be time-consuming and expensive. At Sunny Coast Car Keys, we offer a faster and more convenient alternative. We’ll come to you, diagnose the issue on-site, and restore communication between your key and the car’s start system, without needing to replace your keys or ECU in most cases.

Other LandCruiser Models with Known Key or ECU Faults
While the 200 Series is the most common model we’re called out to assist, it’s not the only Toyota LandCruiser that experiences key or ECU-related issues.
Some 100 Series LandCruisers, particularly those with aftermarket immobiliser systems or key upgrades, suffer from key programming mismatches or transponder communication faults. These can lead to intermittent starting issues or complete immobilisation, particularly after a flat battery or ECU reset.
Owners of the LandCruiser Prado, especially the 150 Series, have also reported problems with the proximity system not recognising the key when inside the vehicle. Although less frequent than in the 200 Series, these faults can also stem from internal antenna failures, ECU communication problems, or software glitches that prevent the system from verifying the key signal.
We’ve also seen issues in newer LandCruiser 300 Series vehicles, although these are often under warranty. Still, when you need fast diagnostics and don’t want to wait days for dealership availability, we offer an efficient alternative with the right tools for the job.
