Reset value for key in redis

I am storing some values in redis like for key: 1 the value will be 

{"counter":1,"counter1":2}

Now I need to reset value of counter while the counter1 should be remaining same.

To increase counter I am use the command SETEX mykey 60 redis .

But it will also reset the value of counter1. So is there any way I can reset one value for a single key.

Let me know if I need to add some more info.

Instead of string you may use hash, then it will be easy. you can increment by some other value, delete counter etc etc. Each key in your json will be hash field.

127.0.0.1:6379> hset mykey counter 1 counter1 2
(integer) 2
127.0.0.1:6379> hgetall mykey
1) "counter"
2) "1"
3) "counter1"
4) "2"
127.0.0.1:6379> hset mykey counter 25
(integer) 0
127.0.0.1:6379> hgetall mykey
1) "counter"
2) "25"
3) "counter1"
4) "2"
127.0.0.1:6379> HINCRBY mykey counter 15
(integer) 40
127.0.0.1:6379> hgetall mykey
1) "counter"
2) "40"
3) "counter1"
4) "2"
127.0.0.1:6379>
