I lost the key for ignition what do i need to do

have a new ignition switch installed with new keys and get it programed to the car.

you damaged the ignition switch and it will not recognize key you have to replace the tumbler and ignition switch the key acts like an electronic switch in most modern vehicles put key in and its recolonized and will turn and start vehicle ---damage to key or tumbler sets off anti theft and you have no start ---in future dont try to hot wire or pop ignition when keys are lost (thats all hollywood) go to dealer with vin and proof of ownership and they can cut you a new key

Duplication of keys may
be performed at an authorized dealer (or locksmiths) or by using the
Customer Key Programming procedure.

DIY, takes 1 key , good, called a valid key, in the below text.
You can program new keys to the system if you have two
valid keys by doing the following:
1. Cut the additional Sentry Key Transponder blank(s) to
match the ignition switch lock cylinder key code.
2. Insert the first valid key into the ignition switch and
turn the ignition switch ON for at least 3 seconds but no
longer than 15 seconds. Turn the ignition switch OFF and
remove the first key.
3. Insert the second valid key and turn the ignition
switch ON within 15 seconds. After ten seconds, a chime
will sound and the SKIS indicator light will begin to
flash. Turn the ignition switch OFF and remove the
second key.
4. Insert a blank Sentry Key into the ignition switch and
turn the ignition switch ON within 60 seconds. After 10
seconds, a single chime will sound. The SKIS indicator
light will stop flashing, turn on for 3 seconds; then turn
off.
The new Sentry Key has been programmed. Repeat this
process to program up to a total of 8 keys.

If you have only one key and you lost it then you will have to change -ignition -boot-doors and fuel door . Have a locksmith look at it as there may be numbers that he can cut a key from

to reprogram new key first you need to use 2 factory program keys.place first factory key in the ignition first turn ignition on for 3 seconds. then turn off ignition then install second factory in the ignition on position for 10 seconds.when immobilizer warning lamp begins to flash a acoustic signal is emitted.within 60 seconds. switch ignition off and remove key.then insert new key and switch on for 10 seconds a acoustic signal is emitted and immobilizer warning lamp remain illuminated for 3 seconds indicating programming completed.if all fails dealership has to reprogram new keys.

The code was only on the key, no where else. Sorry

A key code is stamped on the lock cylinder to aid in replacing lost keys.

if u notify dealer with vin number they should be able to cut u a new key --if ur key had a electronic chip in it still would need to notify dealer ----if u want to replace ignition switch the switch runs about $130 if electronic more -then u need to add on the price of installing it $65-75 an hour labor cost-- some not many lock- smiths do automotive ignition keys [non electronic ] from vin number

Go to any GM dealer ship with proof of ownership and the registration/title of this truck and keys can be made
