My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello. It would appear that the security system for this vehicle does not allow reprogramming for a new remote through any regular procedure. Some vehicles allow reprogramming of remotes and keys by pressing a series of buttons in the correct sequence or timings. Reprogramming a remote for this vehicle requires a specialized scan tool that can communicate with the security system. I would recommend taking the vehicle to a dealership or shop that is equipped with the proper tools required for reprogramming.

Programming a Single Key

Oil leaking from under car and "remote control car" sound when car is first started for a few minutes until it warm up.
ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.

In a keyless entry car, can you also have an alarm say auto watch alarm system installed?
ANSWER : Hello. From what you describe it would appear that the aftermarket alarm system may be having an issue. If the alarm has done this since it was installed then it may be possible that it is wired improperly, or that there is an issue with the alarm system control module. It may be possible that the two alarm systems are interfering with each other somehow, perhaps due to an issue with the transponders or remotes. I would recommend referring to the alarm system manufacturer, or the shop or technician that installed the alarm for more specific support or instructions.

ANSWER : Hello, thank you for writing in. If the new battery has also failed to hold a charge, the alternator is likely not working correctly. You can test the alternator at home with a voltmeter, or you can remove it and have it tested at most automotive parts stores. It will need to be replaced if it has failed. You will also want to make sure all of the electrical connections are clean, dry, and tight. For more help testing or replacing the alternator, contact our service department to schedule an appointment.

ANSWER : There are reports that the replacement alternators will not communicate with the engine computer and will not charge correctly. I recommend using only the manufacturer approved replacement part. It can be new or remanufactured but approved for use in the vehicle. Some lower cost alternators on the aftermarket will have charging problems since they will not communicate with the ECM on the vehicle and will stop charging.

Power steering loss, no belts are turning but the car is running fine. I also have a soft pedal. Whats wrong with my car?
ANSWER : I have only seen this situation once in my 30+ years and it turned out to be a broken crankshaft pulley. Belts are driven by the engine. The crankshaft pulley spins the belts, which in turn spin the air conditioner compressor, power steering and water pumps, and the alternator. The vehicle should be towed to your local repair shop and not driven. Without the water pump spinning to circulate the coolant, the engine will quickly overheat and result in more extensive damage.

My car will not start Intermittently. I purchased a new battery 2 weeks ago and yesterday the car wouldn’t start. Got a jump and
ANSWER : The issue you are having is probably due to an intermittent fault in the starter motor itself or a deficiency in the starter electrical circuit, for example a large voltage drop due to a poor ground or a high resistance connection. These issues can be readily diagnosed and resolved on a mobile basis if you request a hard starting diagnostic. If you request that diagnostic, the responding certified mechanic will get this resolved for you promptly. Based on Toyota’s Factory Service Manual, the battery should not be disconnected if the vehicle engine is running. The battery acts as a large resistive voltage sink and consequently taking the battery out of the circuit, while the alternator is still running, can create a voltage spike on the car’s electrical system which is not good for voltage sensitive components such as the engine computer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
