09 canyon. Locked with fob ate lunch then fob won't work. Tried 2 other fobs and none wil lock or unlock doors

don't have 2 fobs?
it cam with 2,
and the battery must be good.(for buttons to work on fob)
never run any car with only 1 fob or one key.
or get locked out.
are you saying the metal cut key end (pure mechanical ) failed?

my car has a real key with a a transponder inside .
it can open 2 ways, the keyfob buttons, (takes a good battery)
and the key metal end.

get a spare fob and program it.

now you have 2 like you should.

Your FOB has gone bad. Try your other FOB just to make sure and let me know ....

a. When you lock the doors (with the Switch) with you inside... do they stay locked?
b. Do your Doors lock automatically when you put it in gear?

Have you tried using a Different FOB (Remote). If one Remote works properly and One Unlocks the Doors after locking... you have a Defective (FOB) Remote

The problem is not the actuators, the fault lies in the central locking control unit under the dashboard, behind the glovebox, on the firewall. The CLCU is mounted with the connection terminals to the top resulting in condensation going onto the printed circuit board inside, if the damage started a while ago there is only 3 ways to go.

1. specialist firm to repair the CLCU.
2. Replace.
3. (As I did) buy a cheap remote control receiver with keyfob/s. Cut all wires off the multiplug, there are four pairs, a permanent live and permanent earth. Test each wire to earth on the van to identify the permanent earth FIRST. Then test pairs of wires across 12v/Earth noting which pairs actuate which lock.Isolate in pairs noting which wire has to be live to lock, (Reversed it will unlock) wire each pair into the relay on the remote receiver using the relay to changeover the polarity to each pair You will then be able to Lock/Unlock all the doors, throw the old CLCU away and mount the RCReceiver eslewhere to keep it dry. each door individually. I bought a 2 way RCReceiver and can lock/Unlock front doors seperate the the rear ones which is of far more use! Any decent electrician will tell you how to wire the relays. Job Done..... (100% Sure)

Try reprogramming the fob. You can find videos on youtube

please go to the alarm or dealer shop to replace or re program

If the passkey is messed up, there will be a light on the dash that says security, or have a picture of a car with a lock thru it. If there is no light when the key is turned forward, then its NOT a passkey problem.

You are going to need to check the power lock control moduel on the inside of the door panel. If the FOB appears to be working but the doors are not unlocking, you need to check this. I would also replace all fuses that control the locks. If both of these devices check out ok, you may need to replace your FOB. To check your power lock control moduel, manually lock and unlock your doors by pressing the lock button on the inside of the door. If it does not work, it is either the fuses or the power lock control moduel. If it works, your FOB has gone bad. Hope this helps! Please rate 4 thumbs up!

Insert key into door barrel or ignition lock and turn key, whilst doing this press the unlock/lock button, the led on the dash should flash to indicate this has initialised the key to the car, then remove key and test operation of remote. If this fails then a new remote plus coding to the car by your dealership is needed

It sounds like your key fobs need to be reprogrammed. There are two ways to do that. The first way is to go to the dealership and let them do. The second way is to manually do it. This should work. Get inside the truck and close the door. Apply the parking brake and cycle the key on and off four times. If it enters the program mode either the horn will sound or the door will lock and unlock or vise versa. Press and hold both the lock and unlock buttons at the same time. If the key fob reprograms, the locks will lock and unlock or vise versa. Turn the key off and try to lock and unlock the truck with the key fob. If it works then your good to go. I hope this is helpful.
