Replace. Keys are not the same
The dealer can replace it using the VIN number.Acompetentlocksmith can make keys for the vehicle. Depending on the year of the Sequoia, if all keys are lost, the dealer will tell you that the computer must be replaced. This is not entirely true. Some locksmiths offer an immobilizer reset service which will generate keys for the existing computer. The dealer is not capable of providing this service, so they will often tell you that it can't be done and that the computer has to be replaced.
what do you do when the keys on the keyboard are pressed and the computer displays repeated characters
Well since you asked this question you must of used the keys on your laptop/computer! So you must of had the sense to count them...Total Keys = 84, but it depends on what computer you have....

There is one way to fix computer keys that don't work. Since computer stores don't sell individual keys, the only way is to buy a new whole keyboard that is a better version than the other ones so keys won't get broken.
