If your Mazda Protege`s key won`t turn, check to see if the transmission is in Park. Many models will prevent the key from turning if the car isn`t in park when turned off. Make sure your car`s parking brake is enabled before you do anything else.
Turning the wheel in the opposite direction can release the lock and enable you to take the key out of the ignition. Jiggling the key – Another easy method for removing a stuck key is to push down on the key cylinder with your left index finger while simultaneously jiggling the key with your right hand.
Dead Battery

To work correctly, the ignition mechanism is powered by the battery. If the battery fails, the ignition will automatically get locked up. Then you won`t be able to pull the key out of the ignition.

The most common reasons a Mazda 3 key won`t turn are a binding steering column/lock, an ignition switch issue, or a problem with the ignition key. Search our network of RepairPal Certified shops near you to speak with a technician about your issue.
Try gently turning the steering wheel from right to left, while simultaneously turning the key carefully in the ignition. If this fails, try rocking the wheel instead, all while wiggling the key gently.
Dismantle the plastic cover below the steering wheel which houses all the electronics. Then insert a screwdriver into the ignition flaps and force it in using a hammer or by using a drill first. Then turn the screwdriver in the same direction you would as the car key. This will start the car.
To turn the ignition switch to the LOCK (0) position, the shift lever must be in Park, and you must push the knob or built-in key in slightly. The shift lever must be in Park before you turn the ignition switch knob to the LOCK (0) position or remove the built-in key from the ignition switch.
If some keyboard keys stop working on your device, it doesn`t necessarily mean they`ve malfunctioned and need to be replaced. Sometimes, keys cease to respond simply because the keyboard drivers go corrupt, you disable some keys mistakenly, or the keyboard settings get misconfigured.
Car key sensor is not working: If the key is not working at all, it may be due to the drained battery, faulty fob, low car battery, or faulty keyless entry system (if applicable). You can try replacing the fob batteries, diagnosing the fob or towing the vehicle to a service centre to fix the issue.
Press the start button once without depressing/pushing the brake to activate the vehicle`s accessory/battery mode. For vehicles not equipped with the smart key system (traditional key): Turn the key in the ignition system to the first position to activate the vehicle`s accessory mode.
You can replace the ignition switch yourself, but it`s not an easy task: you will have to remove the steering wheel and work close to the airbag – which can be dangerous. Don`t hesitate to call a professional mechanic if you`re not feeling confident.
Master key systems have been around for some time. They enable property owners to decrease the number of traditional keys needed to effectively manage a facility. In short, a master key system allows one keys to open multiple different locks. At the same time, more than one key can open the same lock.
The thief may not have it, but if the vehicle is unlocked, it can be stolen. It`s also entirely possible to hack keyless fobs. Devices can be used to capture and copy the signal from a key fob that`s inside the house. The signal can then be transmitted to the car, unlocking and starting it without the actual key.
However, as new cars are made so is new anti-theft technology such as transponder chips. These small chips placed inside the keys mean that the ignition can not start with a different key, even if it has managed to open the doors.
Unfortunately, there`s no real way to start a car without the transponder chip. Although you can use a key that doesn`t have the right programming to open your vehicle`s doors, you need to use a correctly programmed key to turn ON your vehicle engine.
WD-40 removes carbon residue and keeps moisture away from spark plugs and spark plug wires. WD stands for Water Displacement, so if your spark plugs are wet or you need to drive moisture away from ignition distributors, WD-40 will do the trick.
Vaseline

A staple in many bathroom drawers and medicine cabinets, Vaseline is more commonly used to combat dry skin. But the same greasy, gloopy texture that helps it moisturize can also help it act as a last-minute replacement to WD-40.

The ECM controls the ignition system and distributes the electrical power to each individual cylinder. The ignition system must provide sufficient spark at the right cylinder at the precise time and do it frequently. The slightest error in timing will cause engine performance issues.
For your safety, the steering wheel has a lock that activates if someone moves the wheel when there`s no key in the ignition. This makes the vehicle harder to steal. However, if you`ve moved the wheel before turning on the car, the lock may still be in place.
The most common faults are the battery, battery cable, ignition switch, battery terminal, or a wiring harness fault. If the vehicle started properly before the ignition was removed and after the repair was completed the problems started then the fault may be related.
First, try lubrication. A lubricant can help your key all over and penetrate into the lock to loosen whatever is making them stuck. Spray lubricant will typically do the trick. If you can`t find any, WD-40 works as well.
Like anything else relying on a battery, your car key fob can die—often at the worst time. Thankfully, these batteries are easy to replace.
Most remote car keys use lithium ion coin batteries, which have a long, but not limitless, shelf life. A dead battery is usually the primary cause of remote car key failure, so should be the first thing you check if your remote car key stops working.
