Sgh-e250i function keys dead All functional keys, except the power on/off key, not responding. Number keys are working.

You failed to mention the model number, however, if the unit is truly dead, with slight exceptions, a factory reset will do nothing for you. If you need more assistance, or would like to inquire about repairing your Pioneer, please visit my website at audioserviceclinic.com, and contact me there. Thank you.

REMOTE KEY INITIALIZATION For this type of key.


The initialisation of the FZV keys is required to establish the Lock/Unlock signal synchronisation with the GM V. The initialization procedure provides the GM with a key identification number and a "rolling code" for each key. If the initialisation is not performed, the GM will not respond to the key signals. Up to 4 remote keys can be initialised. They must be initialised at the same time. Key initialisation is only possible with the vehicle unlocked.

Procedure:
1. Close all doors and have all keys available.
2. Using key number 1, turn the ignition switch to KL R, then switch off within 5 seconds and remove the first key.
3. Within 30 seconds of turning the ignition switch to "off" Press and hold button #2 .
4. While holding button #2 , press and release ("tap") button #1 three times within 10 seconds.
5. Release both buttons. The LED in the key will flash momentarily. The GM will immediately lock and unlock the doors signalling a successful initialisation.
6. If additional keys need to be initialised repeat steps 3 - 5 within 30 seconds.
7. Switching the ignition to KL R completes the initialisation.

SERVICE NOTE:
The key memory function of the GM responds to the key identification number of each key. If the keys are not initialised in the same order prior to initialisation, the key memory functions activated by the keys will not be assigned correctly. Always initialise the keys in the same order.

The upper symbols on the keyboard are called function keys usually not expected to respond when pressed. functions keysy are ysed to control the computers settings either when malfcuntions occur or computer requires alternations to another feature possibility. Every available keys are displayeable besides fucntions keys on user productivity programs.

For integral powers of ten, use the EE key, just above the 7 key. For example, to enter 1.3 time ten to the fourth, press 1 . 3 EE 4

To raise e to a power, use the e^x function (the shifted function of the LN key on the top row). For example, to calculate e raised to the 1.2 power, press 1 . 2 2nd [e^x] =

To raise any number to any power, use the y^x key, just above the divide key. For example, to calculate 3 to the 5th power, press 3 y^x 5 =

Hope this helps. If you still have questions, please feel free to respond to this post.

Hi, What controls the keys on phones are little IC chips inside the phone on the phone board. When it gets damaged it affects the number keys. Replace the IC chips are the number key will function.

Take care.

Hi,you will have to replace the flex of the phone.
The flex make the touch pad to function,also the functioning of the number keys.
When you replace the flex the touch pad and the key will function again.

Thanks for using fixya.

You probably have your flex cable broken.. see this guide.

Touch pads are not very reliable. I have seen a lot fail.
A computer repair person will need to replace it for you.
My advice is to stick with a USB mouse. Or if it is under warranty, take advantage of that warranty.
Best of luck.

my upper key pad not functioning except call and power keys what should i do? and some times hanging on white screen. pls tel me the solution
