How can you start a Toyota Highlander manually?
The majority of cars have workarounds that make key fobs less of a need and more of a luxury. Despite their seeming necessity. To start your Toyota Highlander, you can actually utilize the metal key that is housed inside the key fob.
To start your Toyota Highlander with a dead key, adhere to these steps:
- Use the metal key to unlock the door on the driver’s side.
- Once seated, depress the brake and push the start button while keeping your key fob as close to the push-start button as you can.
- To release the metal key, first press the button on the bottom of your key fob. After that, remove it from the fob.
It’s uncommon for the key fob to fully die because they don’t require much power. Because of this, using these methods should typically enable you to start your vehicle without a completely functional key fob.
But keep in mind that your battery can be on the verge of dying completely. Change the battery as soon as you can to prevent any major issues down the road.

Why would my Toyota not start?
Fuses
Although not all cars have a fuse that is linked to the starting mechanism, this possibility can be swiftly ruled out with a fast check of the fuses.
BatteryThe link to the rest of the car is lost if the connections on your battery start to deteriorate. This may prevent you from beginning. Try starting the car after cleaning the posts.
The battery can also be dead. Check the cranking amps with a battery tester to check if they are low. In the absence of a battery tester, you can check your battery by jump-starting your car. If it starts straight immediately, the battery needs to be changed because it is damaged. Change it, then tidy up the connections. (This page includes advice for changing the battery and jump-starting your car.)
On/Off Switch
The ignition switch may be to blame if the battery is functional but your car won’t start. Look for the red warning lights on your dash and turn the key to the ON position. The ignition switch may be to issue if you don’t get any lights but your battery is functional.
If you notice dash lights, try turning the key to the on position to see if the lights disappear. Your ignition switch is functional if the lights go off.
Beginning Connection
The starter might become corroded and prevent the automobile from starting. Hold a circuit tester lead on the starter wire to check the connection. It will be the smaller wire between the two. Keep your distance from the engine’s moving parts, and have a helper turn the key. Verify the starter’s current. The starter needs to be replaced if there is current flowing through it but it is not spinning. If the starter is in good condition, then the issue is elsewhere.
The ignition system should be checked next because there’s a chance you’re not getting any spark. However, if you are certain that it is the starter, you might find this post useful.
Remove the distributor cap and look inside to see if there is any dampness. Even though this is most likely not the problem, it is a good idea to look for cracks or moisture. If it is cracked, repair it by drying it out and putting it back on. Check to see whether the car starts.
Coil WireYour car may not start if the coil wire is broken or shorted. Make sure the wire is not split or fractured by looking at it. For continuity testing, use a circuit tester.
When your car has power but won’t start, what does it mean?
When a new engine won’t start, the battery is typically at blame. However, a dead battery and an alternator are mostly out of the question if the car is still getting electricity. Some batteries could ship from the factory with a lesser charge retention capacity. This is a manufacturing flaw, and the warranty allows for a replacement.
However, it is simple to believe that the battery is in perfect condition if a car won’t start but still has power. It can be very deceiving, especially if the lights, horn, and other electrical components work well. This is because not all peripherals use the same amount of energy.
To start the engine, however, the starter motor requires a lot of power. It’s possible that a battery nearing the end of its useful life won’t be able to power the starter motor sufficiently. Additionally, some electronic ignition systems start out by using a lot of energy. But since they draw less power from the battery, accessories like lights, horns, and radio systems might function.
Everyone may become confused at this point. So, get your multimeter and examine the battery terminals if your car won’t start but has electricity. It should ideally read 12 volts with the engine off, if not extremely near to it. The battery is on the verge of dying if not.
Start the car, switch on most of the accessories, and read it once more. When you press the accelerator, the voltage shouldn’t drop; instead, it should rise to 13.5 to 14 volts. If this doesn’t happen, there might be a problem with the alternator. When a car won’t start yet has power, this is the most typical problem.
Try Shifting the Shifter
Try to start the engine while keeping your foot on the brake and shifting into neutral. Move it back to park and try it again if that doesn’t work. Electrical contact inside the transmission range selector can occasionally be restored by moving the shifter (also known as the neutral safety switch).
My Toyota Highlander will start without the key fob.
I’m sorry to hear that the key gave you trouble. Your Toyota Highlander key fob most likely has a dead battery. But don’t worry! I’m glad to assist you.
Just follow these steps to start a Toyota Highlander without a key:
- On the side of the key fob, look for a push button.
- However, the car will start without any problems if you take the key fob and put it right on the push-button start as you press it in.
- At this point, you might have noticed that the car lacks an ignition key slot.
- The physical key will come out when you press the button firmly.
- You can enter the car by physically opening the doors with the physical key.
When you can, visit a store and purchase a CR2032 battery, which is what practically every key fob, including those for Toyotas, uses.

If the battery in my key dies, would my car stop?
This issue has been foreseen by automakers ever since the key fob was created. Nothing will happen if your key fob dies while you’re driving. Simply because the key fob is a locking and starting device only, the automobile will continue to run. The key fob has no influence over the ignition or engine once the automobile is moving.
Even though you’ll need to go to a general store or pharmacy to get the battery, replacing the battery in your key fob simply takes a few minutes if you’re pressed for time.
Why not take the time to renew your auto insurance at the same time as you’re replacing the batteries in your key fob?

My car won’t start, but the battery is fine. Why?
Your starter may be the issue if the battery appears to be in good condition. A starter is a little motor that uses battery power to pull current in order to start an engine. When you turn the key in the ignition, you can hear a clicking sound if the starter fails or malfunctions. In some cases, loose connections are the issue, while in others, a new starter may be required. There is no assurance that jumping a car will fix starter issues.
Why won’t my car start despite a good battery?
Ever ponder the cause of a non-starting car? A weak or dead battery could be one of the causes. Use a battery tester to check the battery’s strength if it can measure cranking amps. If the battery cannot be tested, attempt jump-starting. If the car starts immediately away, a dead battery is most likely the cause of your issue. To guarantee proper contact, charge the battery and clean the terminals and cable connectors. If you try to jump-start your automobile and it won’t start, your starter, alternator, or another electrical system part may be broken. Make careful you read and abide by all handling and safety directions provided on the battery on our website.
When the battery is healthy, what prevents a car from starting?
It might seem simple, but if your battery, spark plug, and alternator are in good shape, you should check to see if your automobile has adequate fuel.
What can you do about it?
Before you start driving, check that your gas tank has enough fuel, and make an effort to keep it filled up.
During the winter, a fuel line in your car could even freeze. Keep in mind that the more space there is for water vapor to condense and freeze inside your car’s gasoline line, the more empty a gas tank or fuel tank there is.
Finally, have your gasoline reading gauge checked if it frequently runs out to the point that your car won’t start. The gauge can be defective and unable to provide you with the appropriate reading at the appropriate moment. Any other underlying problems with the fuel system will also be found by a mechanic.
How may a sensor prevent an automobile from starting?
An essential tool for tracking the crankshaft position and determining engine RPM is a crankshaft position sensor, or crank sensor. If the crankshaft position sensor is malfunctioning, the automobile won’t start. The crank sensor may malfunction or experience electrical issues. The car can stall or not start as a result of this. Frequently, this occurs sporadically. A scan tool or a multimeter can be used to test a crankshaft sensor. Crankshaft position sensor: read more about it here.
Similar in operation, the cam sensor or camshaft position sensor measures the camshaft’s rotation. Two cam sensors, one for each camshaft, are used in automobiles. Many cars, notably older Nissan and Chrysler models, have issues with the cam and crank sensor.
